AFAIR Jack had asked for Buster... ASCII is Stretch.

Wheezy: mcelog not getting notified of ECC errors anymore?

After installing Wheezy (using FAI, so the setup is essentially unaltered),
one of my machines doesn't report memory errors via mcelog anymore. Error
messages go to syslog instead:

Or use the netboot CD, and your own transportable mirror if you don't want to

You have seen some sensors output from a 627 chip, haven't you?

  Also, is any chance to configure the sensors.conf from data read from BIOS

 No.
 
 The fan speed should be fairly simple in general.  It is usually either
 correct or it has to be divided by 2 or 4 to make it correct.  The
 maximum and minimums for the alarm state should be set based on the
 actual speed of your fan when it works normally.
 
 For voltages, the sensors I have worked with will read correct for any
 voltage under 4V, but need an offset and multiplication factor for any
 voltages over 4V (since they use a resistor network to scale the voltage
 down into a 0 to 4V range for the sensor).  To get an accurate reading
 really requires knowing which resistor values were used.  Of course you
 also need to know which voltage is supposed to be on each input on the
 sensor since they could really be used for anything the board maker
 chooses.

There are a few very nice design documents for sensor chips out there
(IIRC I grabbed the one for a WD...627HF - did I get the number right?)
which shows that there should be a linear dependency of the sensor input
reading on the voltage measured, indeed. For negative voltages, and for
some positive ones too, there's not only a multiplier/divider but also 
a bias voltage.
Which means that the raw register reading (the one you get in the /proc
or /sys filesystem) is always positive, and you've got to fiddle with
a and b in

register_value = a * voltage + b

or, reversed, 

real_voltage = 1/a * register_value - b/a

That's exactly what the conversion formulae are for.
If one knows that resistors usually don't come in arbitrary values but
follow some rules (look for E series, common values are 6.8 and 10, 
times a power of ten) it's easy to guess.
Note that a single data point (taken from BIOS readings) doesn't allow
to determine a and b simultaneously!

Since your board seems to have plenty of sensor chips one has to expect
that not all inputs are wired (and their readings may be nonsensical).
There's the ignore option to fix this.

Sometimes the same voltages are fed into different chips.

This is not exactly true: apt-key list will tell you that the 2006 signing key
will last more than 10 weeks from now. But nevertheless it's a good idea to
have a longer-lasting key for the then stable release.

 Hello,
 
 Trying to get sensor to work with an IntelS5000VSA board.
 Have etch with kernel 2.6.17 (x86_64) installed.
 
 lm-sensors and sensor-detect recommends to install:
 i2c-isa
 i2c-ipmi
 bmcsensors
 
 I can modprobe i2c-isa, but not i2c-ipmi or bmcsensors.(missing)
 Looks like I should install module ipmi_si, but attempting
 from modconf or simply modprobing it results in a hang.
 Have to reboot to kill it off.

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.

  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.
 
 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.

Great! You now might be interested in the ipmitool-devel list (hosted
by the ipmitool sourceforge project)

 Thanks,
 Mike

You're welcome. It's nice if someone else is half a step ahead, isn't it? :-)

 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 http://www.debian.org/mirror/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.

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

 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?

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

Cheers,
 Steffen

 How to activate SMART at booth with amd64 etch raid1?
 
 Apparently
 
 start_smartd=yes
 
 in /etc/default/smartmontools does not work (unlike in non-raid i386 etch pc).

Log messages? I suspect you'd have to change your /etc/smartd.conf from
AUTODETECT to specific addressing the disks (including the -d ata flag).

 To check hds i had to command from terminal window:
 
 #smartctl -s on -d ata /dev/sda
 
 #smartctl -s on -d ata /dev/sdb
 
 Which is the way to get SMART activated at boot?

smartd tries to start, but with AUTODETECT enabled it probably does NOT
detect the disks (since one has to go thru libata for this).
This behaviour might change with the next release of smartmontools; please
check with their sf.net site.

 Steffen

Re: Can't install -- locks up

 I can't install debian, the installer just keeps locking up / hanging

Randomness usually points at random sources, not the ones that are
properly under control: external temperature/airflow, bad CPU cooling,
or failing capacitors on the board.
Also RAM sockets can be involved.

 MB: 9NPA EPoX nForce 4 Ultra Motherboard
this is supposed to be new enough not to suffer yet from failing C's
 RAM: 3 sticks PC 2700 (1.75 gb)
did you run memtest86+ ? the modules might have moved slightly
 HD: Samsung Sata 2
 CPU: AMD X2 dual core 3800+
if cooled properly, AMDs should be OK, check hardware monitor in BIOS
whether there are abnormal temperatures or voltages

 Debian:
 Etch/testing netinstall from Aug 17, 2006
 
 Selected ftp.debian.us (something like that) mirror
 Created 2 partitions (1 swap, 1 reiserfs)
 Setup SMTP
 Hung on lib6 installation
 
 attempt #2: hung on grub-install (hg0)

can you compare the uptimes?

 Not sure what is wrong. RAM timings with motherboard (ram is good
 though, I didn't upgrade it), bad hardware, bad installer version on
 that day, etc.

I'd blame the installer build last...

Re: Cannot install a bootloader

 Hi All,
 
 I've trouble installing the bootloader (both grub and lilo fail). I'm 
 using the netinstall cd-image to install. My first idea was a problem 
 with my RAID controller (Adaptec 2020ZCR, running a 4 disc raid 5 array) 
 but it even fails to install a bootloader to a floppy disc. So I think 
 it's a general problem, instead of a hardware problem.
 
 It always returns the same error message:
 
 The file /boot/grub/stage1 not read correctly.
 
 The thing I found out is that the new / filesystem is still mounted 
 under /target, but I guess this is normal while installing...? (never 
 bothered to look, since it always works out fine).

I've seen this error message a few times.
grub must be installed from a chroot environment (which should be true
in your case).
grub must find a *correct* mtab to resolve hard disk partitions.
(it's a bit tricky since the /proc/mounts trick appears not to work)
A leftover device.map may confuse it as well.

 Thanks for your reply. Only I'm not sure what to do now... I've chrooted

 Could you give me another hint?

Run the script by sh -x and look what exactly is being extracted for 
the (hd*,*) values, and compare with your setup

With amd64, I'm seeing the same, most apps depending on gnome 2.14 and
kde 3.5.2, both of which aren't complete yet. This has been holding up
upgrades for about a week now.

To me, it looks like the buildds are not keeping up and/or there's a problem
with the sid-etch transition. Since I installed sarge long ago, and 
dist-upgraded
to testing from there, I keep having a stable and working system (most of

this part should read /debian/. And yes, it looks very reasonable.

 With 2 * 1GB, you get 6.4GB/s memory bandwidth.  With 1 * 2GB, you get
 3.2GB/s memory bandwidth.  I think that is a reason to prefer the
 pair 1GB sticks
 
 Socket 939/940 AMD's have dual channel memory controllers to get double
 memory bandwidth, but only if you put in at least two sticks of memory
 (and into the right slots on the board).

Wouldn't this mean that, in a dual CPU system, one should better use 4 mem 
modules?
