I don't know what "partial" means; if you want to select "etch" and "amd64",
debmirror is your tool of choice.

It makes sense since debmirror will clean up obsolete packages. Just run
it once per night/week/whatever ...

Great! You now might be interested in the ipmitool-devel list (hosted

I was following with interest the thread about system freezes, but it seems to 
have dried up. So, I was wondering if people have found a fix. Sorry for this

long post...

My system (HP nx6125 laptop, AMD Turion 64, ATI chipset, ATI Radeon Mobility 
XPRESS 200M) started to have "random"  freezes shortly after the xorg 7.0 ->  
7.1 transition in etch. The symptoms seem to be very similar to those 
described in the "System freeze" thread of a few weeks ago. I first noticed 
this a few weeks ago when I was viewing my  system logs and scrolling by 
holding down the arrow keys. Sudden freeze during scroll.  Reboot and 
execute "less /var/log/syslog". I scrolled down a bit more and freeze again 
(during scroll). 

I did several experiments in the interim. I just booted the machine and left 
it on. Eventually the screensaver would come on, work for a few minutes and 
then freeze. Sometimes I could prolong the time before a freeze by 
interrupting the screensaver with a move of the mouse shortly after it came 
on, but eventually  the system would freeze, typically within a timescale of 
hours. This happens with the radeon xorg drivers, the ati xorg drivers and 
proprietary fglrx 8.30.3.


Today, I decided to use the laptop for useful purposes (i.e., not diagnose 
bugs ;-)). I was editing a moderate sized file with kate and doing the 
typical, scrolling up and down with mouse and keyboard. I experienced two 
freezes while doing a long scroll by holding the numpad arrow key down (so 
that the keyboard repeats) and one while scrolling with the synaptics 
touchpad (mouse pointer). I briefly switched from fglrx to the ati driver, 
rebooted, turned away from my laptop to do something else and it froze up.


In every case there is nothing written to the system logs. The machine will 
not even respond to ping requests once frozen. It needs a complete reboot to 
get it going again.


I have run memtest86+ for hours without errors. The probability that this is a 
software/Xorg bug is high, given the sudden increase in reports of this kind 
of late (so I'm not ready to remove memory chips from my laptop yet...).  

Google has been unhelpful. This seems to be a common problem on various 
distributions including ubuntu. The causes seem to be many and varied: 
presence of powernow-k8 module (I use this), network and usb mouse related 
(http://ubuntuforums.org/showthread.php?p=1738666), Nvidia related (see 
previous thread), clock-skew related (powernow-k8 ?), etc. However, there 
seems to be no definitive answer as to what the cause is, or what the fix is.


In my experience, it seems that it might be triggered by prolonged scrolling 
or mouse  activity (or lack thereof?). But this is such a common user 
activity that my experiences could just be coincidence. I have not managed to 
get kernel 2.6.19-rc5 to work properly on my laptop, so that fix (mentioned 
above) is not an option for me now (does it really work?). 

I am currently running debian etch (amd 64) with xorg 7.1 and a custom built 
2.6.18.2 kernel. I autoload the powernow-k8 module and use the 
kernel "ondemand" governor by default. I have tried with a range of older 
(custom built) kernels going back to 2.6.17.x and nothing changes. None of my 
32bit debian etch desktops (which do not use frequency scaling) exhibit this. 
None of my colleagues' 32 bit debian etch desktops (which do not use

Any help would be appreciated My apologies again for the long post.

Richard 




  
As mentioned earlier I would try to downgrade the python-central to 
0.5.8. Seems like you started to have the problem at the same time as 
when 0.5.9 hit etch. When I upgraded to 0.5.9 I could not compile a 
kernel without system freeze.


I also found that the system sometimes froze after running a screensaver 
for several hours - when reactivating the system. So now I have disabled 
the screensaver.


I haven't had a system freeze since.

Pleas try to isolate the problem,

If you suspect of powernow-k8 disable it,

try to work without X for a while

try vesa driver

try change your mouse

try chage your mouse driver...

good luck...

I use Debian almost exclusively on all the servers I control.
Personally I think it comes to a question of choice.

As Regards AMD64 I am putting up a couple of AMD64 Database servers in a
few months, Etch will probably go on those. 

Dapper Drake Im sure might do it as well, but personally, I have no
reason to change away from Debian, never found the need too.

BTW: Etch will probably be more Recent once released than Dapper Drake
(6.06 right?) It was released in June..

Partial Local Repository

[GNU Linux]

Hello all,

I am planning to create a partial local repository for AMD64 Etch but I
don't know the best tool for this.  I downloaded and tried the
anonftpsync  but until now, it
keeps on downloading files.  Any other recommended tool to create a
partial local repository?  I don't want apt-proxy because it requires
the local repository server to have an Internet connection.

Does it make sense that I'm already downloading the packages for Etch
even if it's not yet the stable version?  I'm just preparing Etch
because it will be the next stable version starting next month.  Or
shall I just wait until Etch has been finally released as stable?

Please advise.

Thank you.

I've got vmplayer running. The first release (1.0.0) was easy to install
if you had your i386 chroot libraries in your 64-bit environment's
/etc/ld.so.conf. However the latest (1.0.2) has conflicts with our
32-bit GTK+ libraries and so some workarounds are needed.

You can't install it all in the 32-bit chroot because then it won't
build kernel modules for 64-bit, won't find the right kernel headers
etc.

Here's what I did:

0. Fetch the installer (1.0.2)
1. Install in 64-bit into /usr/local/vmware
2. Install will configure the networking and compile the kernel modules.
This should all work fine.

3. Bind mount /usr/local/vmware into your i386 chroot

4. To launch my XP VM, I use the following script:

#!/bin/sh
cd $HOME/vm
dchroot -d env VMWARE_USE_SHIPPED_GTK=force vmplayer xp.vmx

"VMWARE_USE_SHIPPED_GTK=force" is a workaround for incompatible symbol
versions between our libpng (IIRC) and some libraries included with
vmplayer. It forces it to use their libraries for everything, but then
that doesn't work from 64-bit land for some reason so the chroot is
needed.

Also if you have a dual-core processor you may need workarounds to stop
the BSOD in the Windows guest.

Grab the free VMWare Server 1.0, install it into /usr/local, fire it up, 
create a VM, and install Windows.  After "booting" into Windows, install 
the VMWare Tools to allow you seamless mouse/keyboard movements between 
the host system and the virtual system.

Works like a charm here.

I use qemu on an amd64 system.  I have been impressed with qemu, but I
don't know whether USB support exists.

Grab VMWare player, prepare yourself a windows installation and you'll be

Never tried qemu, but it should do too.

Must be something else that differs. Compare the "dpkg -c" output of

If at all. The only thing I did with my 32bit chroot in the last year
is run mplayer, aviplay or xine for when I needed some non-free codec
the amd64 players can't have.

That is definetly a possibility.

Create /mnt/both-usr/i386, /mnt/both-usr/amd64 and /mnt/both-usr/both.
mount --bind /mnt/both-usr/i386 /usr
or
mount --bind /mnt/both-usr/i386 /usr
depending on the arch (via fstab)

Write a script that generates a md5sum for every file under /usr/ for
both archs. For every matching file move the file into
/mnt/both-usr/both and create hardlinks in /mnt/both-usr/i386 and
/mnt/both-usr/amd64. (Or compare size and then content for each file
that exists in both.) That should give you as much benefit as sharing
/usr/share suggested below without any of the problems.

Only do this for /usr. It is not worth for /etc, /bin, /sbin, ... as
you get problems having them on a seperate partition. You would really
need custom initrd then. Not impossible and probably takes just a few
minutes (hours, weeks) to understand mkinitramfs or yarid or whatever
your favourite tool is. But is it worth it for the few k that could be
shared?

Not all programs have bitness indiferent ~/.foo files. There were
cases where it broke. People consider them bugs so try and keep
reporting any issues.

As for stuff you compile yourself install a 64bit kernel under i386
too or simply just use the one from amd64. Share /boot.

/usr/share/doc is not allowed to contain anything needed to run
packages and afaik free for you to clean up. It should be save to
share /usr/share from the programs point of view if you keep both
installs in sync, that's why it is called share. Dpkg should also work
out fine with files disapearing by the other installation. But
maintainer scripts might die horribly when they call scripts from
/usr/share during upgrades that suddenly are there no more or behave
differently.

I don't think the space saved is worth the risk.

766M/usr/share

Size limitations differ for certain but if you keep it small enough
for i386 that should work. If they differ then you need a mkswap
during boot.

Virtual machine on Debian amd64

[Gudjon I. Gudjonsson]

Hi
   I have made a childish attempt to become a software developer and I found 
out that there is some people out there in the big world using Windows :)
   I need some Windows environment and wine does not help since it does not 
support USB as far as I know. Is there anyone using a virtual machine 
successfully on amd64. And if so, does it work properly?

Regards
Gudjon

Thanks Rodrigo. I've used the bcm43xx module briefly, but have recently 
changed from Linuxant's driverloader to ndiswrapper 1.28. I intially 
suspected ndiswrapper until I had a feeze during a kernel compile where I 
deliberately didn't load the ndiswrapper module :-(.

Hi Richard,

I was having the same problems with my HP zv6000, when I upgraded to
2.6.18... however my is related to the wireless card.. does your note
uses bcm43xx module ? try removing it and testing.

System freeze (again)

[Richard L. Mace]

I was following with interest the thread about system freezes, but it seems to 
have dried up. So, I was wondering if people have found a fix. Sorry for this
long post...

My system (HP nx6125 laptop, AMD Turion 64, ATI chipset, ATI Radeon Mobility 
XPRESS 200M) started to have "random"  freezes shortly after the xorg 7.0 ->  
7.1 transition in etch. The symptoms seem to be very similar to those 
described in the "System freeze" thread of a few weeks ago. I first noticed 
this a few weeks ago when I was viewing my  system logs and scrolling by 
holding down the arrow keys. Sudden freeze during scroll.  Reboot and 
execute "less /var/log/syslog". I scrolled down a bit more and freeze again 
(during scroll). 

I did several experiments in the interim. I just booted the machine and left 
it on. Eventually the screensaver would come on, work for a few minutes and 
then freeze. Sometimes I could prolong the time before a freeze by 
interrupting the screensaver with a move of the mouse shortly after it came 
on, but eventually  the system would freeze, typically within a timescale of 
hours. This happens with the radeon xorg drivers, the ati xorg drivers and 
proprietary fglrx 8.30.3.

Today, I decided to use the laptop for useful purposes (i.e., not diagnose 
bugs ;-)). I was editing a moderate sized file with kate and doing the 
typical, scrolling up and down with mouse and keyboard. I experienced two 
freezes while doing a long scroll by holding the numpad arrow key down (so 
that the keyboard repeats) and one while scrolling with the synaptics 
touchpad (mouse pointer). I briefly switched from fglrx to the ati driver, 
rebooted, turned away from my laptop to do something else and it froze up.

In every case there is nothing written to the system logs. The machine will 
not even respond to ping requests once frozen. It needs a complete reboot to 
get it going again.

I have run memtest86+ for hours without errors. The probability that this is a 
software/Xorg bug is high, given the sudden increase in reports of this kind 
of late (so I'm not ready to remove memory chips from my laptop yet...).  

Google has been unhelpful. This seems to be a common problem on various 
distributions including ubuntu. The causes seem to be many and varied: 
presence of powernow-k8 module (I use this), network and usb mouse related 
(http://ubuntuforums.org/showthread.php?p=1738666), Nvidia related (see 
previous thread), clock-skew related (powernow-k8 ?), etc. However, there 
seems to be no definitive answer as to what the cause is, or what the fix is.

In my experience, it seems that it might be triggered by prolonged scrolling 
or mouse  activity (or lack thereof?). But this is such a common user 
activity that my experiences could just be coincidence. I have not managed to 
get kernel 2.6.19-rc5 to work properly on my laptop, so that fix (mentioned 
above) is not an option for me now (does it really work?). 

I am currently running debian etch (amd 64) with xorg 7.1 and a custom built 
2.6.18.2 kernel. I autoload the powernow-k8 module and use the 
kernel "ondemand" governor by default. I have tried with a range of older 
(custom built) kernels going back to 2.6.17.x and nothing changes. None of my 
32bit debian etch desktops (which do not use frequency scaling) exhibit this. 
None of my colleagues' 32 bit debian etch desktops (which do not use 
frequency scaling) exhibit this. 

Any help would be appreciated My apologies again for the long post.

Richard

Okay, I spoke a little too soon.
There was some intel management stuff disabled in the bios by default.
I enabled, rebooted, and now the ipmi_si module loads no problem.

# ipmitool sensor 

Gives me the info I was looking for.

Thanks,
Mike

Purged lm-sensors and removed the i2c* modules.
rebooted and loaded ipmi_devintf and ipmi_msghandler okay.
However, trying to modprobe ipmi_si still ends up hanging.
Perhaps the server board doesn't support this module?
or maybe there's a conflict somewhere?
Whats really dumb is that even in the MB BIOS, there's no power management
to even look at the CPU temp. So I have no idea how hot the CPU's are running.

cheers,
Mike

If you use IPMI *don't* use lm-sensors. You're calling for trouble.

modprobe ipmi_{devintf,msghandler,si}, create /dev/ipmi0, and use
ipmitool.
