If something is done, Celsius should be default (as the US is brain-dead
like that; nearly everywhere else uses Celsius as the standard) and
fahrenheit as an option.

I wrote a patch for the 'sensors' utility in lm_sensors that did just
that; supplied fahrenheit conversion for the sensors via a commandline
option. Perhaps there could be a config option in the kernel (or a proc
entry/ioctl?) that controls this.

Re: APIC errors ...

2001-04-18 Thread Dr. Kelsey Hudson

Um... Looks like when you clock the BX-chipset out of spec (>100MHz FSB)
you get the error. Since BX wasn't ever designed to be run at >100MHz
these errors are *expected*.

You have a couple solutions: Upgrade the motherboard to one of the VIA
133MHz chipsets (I dont care for the VIA chipset so this really doesn't
strike my fancy) or upgrade to that other Intel chipset that supports SMP;
unfortunately it also is a rambus boardServerworks also has a chipset
out that does dual intel chips at 133MHz; I've heard only good things
about it.

but, from what it looks like, your board is flakey up high...

I'm not about to convert my filesystems over... It's too much a hassle for
little gain. ext2 is faster anyways, IIRC.

The problem disappeared when I installed 2.4.3 release; I think it was a
DRM issue in the kernel that was causing the lockups

Thanks for the help though

 I looked a bit at the source of sysrq handling. I've found there is
 rather big difference between sysrq+b and other killers handling.
 Sysrq+b is just called with pretty straitforward fashion - stops other
 processors on SMP and reboots directly (hardware impulse or triple fault)
 or through the bios - so it just calls for the corruptions.

ah, that would explain it...

 On the other side sysrq+s marks a single variable, which will be tested
 next cycle in the bdflush kernel threads' main loop, and adds bdflush to
 scheduler runqueue list. So it gets possibility to check for emergency
 sync onle when gets next scheduled. Does it ?

 Can you anyhow find something in your logs/console/serial console messages
 like 13.13.2000 kernel : Sysrq: Emergency Sync (this should be present - is
 written within keyboard handler, not after shedule) and what's next logs ?
 We could determine, if the bdflush thread got scheduled and called emergency
 syncing routine indeed.

Nope, there was nothing in the logs.

 As you wrote no of your processes does respond - probably telnet will
 not help. You may try to write experimental programme, that only log
 say current time every n seconds, and see, if it just stopped to
 log messages after lockup-time. If not - it doesn't get scheduled.
 If continues - there's problem with syncing. Again - try, as far
 as i understand, log kernel messages to serial console or alike, because
 the messages should not get written to logfiles - syslogd can't be woken up
 eg.

Telnet's disabled anyways :) Cleartext passwords SUCK. :)
I've got a nifty LCD thingy I can hook up to the serial port and use as a
console if need be.

 Quick help against those corruptions, which comes on my mind, is use
 the reiserfs. I have no real experiences with that and its reliability,
 also as aj followed some of messages in this list about resierfs - it has
 some problems too - but in definition it shoudn't get corrupted by not-
 syncing reboot. But i see this not much helpfull ,cause if you really
 would depend on big reliability, you wouldn't intall 2.3.x-pre kernel :)

I'm not about to convert my filesystems over... It's too much a hassle for
little gain. ext2 is faster anyways, IIRC.

The problem disappeared when I installed 2.4.3 release; I think it was a
DRM issue in the kernel that was causing the lockups

Thanks for the help though

I've noticed a similar situation:

I recently upgraded to XFree86 4.0.3 and have been having nothing but
problems with it. Often times, the machine will crash, with crap shot to
the screen. Howver, the IP stack still functions, routes packets, but none
of the user processes respond. I'll try and hit sysrq-s to sync the disks,
sysrq-u to unmount them, and sysrq-b to boot the machine. Unfortunately,
the only one that responds is sysrq-b, which boots the box without
syncing or unmounting the disks. Not only does that piss me off but it's
led to some fs corruption as well (which pisses me off even more). sysrq-b
is the *only* combination I can get working when this happens. However,
when the machine is *not* locked, sysrq-[su] work fine. Kernel is
2.4.3-pre6 on SMP i686.

Oh, honestly! Think about what you are saying here:

What if you are developing something in an interpereted language such as
perl or a shell script, where you *directly modify the executable file*?

No, this won't work...Not wwithout being annoying as hell.

Re: Adaptec/DPT RAID Drivers [Was: Re: DPT Driver Status]

2001-03-21 Thread Dr. Kelsey Hudson

I've got a SmartCACHE IV...This driver seems not to recognize it.

I applied it to 2.4.2...the patch didn't apply cleanly, however.
I was able to manually patch the makefile to build the drivers for the
card however, but it still didn't want to work.

In any case, if you have any insight on this I'd much appreciate it, as
I'd like to get the card into production ASAP.

 kgcc instead. You should always use this to compile your kernels

That means that there's a bug in someone's driver.
For some reason, the function to decrement the module use is called more
than once when a controlling process releases use of a module. 

This will prevent you from being able to 'rmmod' or 'modprobe -r' it; a
"Device or resource busy" error or similar will result IIRC. 

Submit a bug to the driver maintainer.

Software is only as 'good' as the effort the programmer who wrote it put

It had always been my assumption that non-optical storage media used the

 When it hangs, I noticed a very strange thing.  If I push the power

 Where do cards with PCI-PCI bridges, like multiport PCI ethernet cards,
 fit into this?  I can easily add 3 or 4 extra busses into a box just by
 grabbing a couple extra Intel dual-port Ethernet cards.

Notice the 'also account for anything funny' line. Multiport ethernet
cards IMO fall under this category.

It had always been my assumption that non-optical storage media used the

Make sure your system is free of dust...dust can cause small errors like
this to occur. Also make sure that the temperature of the system is within
tolerable levels. Also, a capacitor on your motherboard could be

Probably not. The errors were there before yo upgraded the kernel; they

Is there a reason you are using a relatively new machine like that with
such an outdated and arcane kernel (and distribution, for that
matter)? I'd suggest you upgrade to a more recent kernel and/or
distribution...it'll be a lot more stable (and not to mention secure!)

see, thats where you and i disagree...I wouldn't call you an end user

buy a PC and expect it to Just Work(tm). Servers, embedded devices, et al

Of course that would be better. The only complaint I have with such a
system is that of backwards compatibility...as long as the legacy device
names are still supported i would have no problem with it at all. 

however, this brings up an interesting question: what happens if two disks
(presumably from two different machines) have the same disk label? what
happens then? for instance, i have several linux machines both at my
workplace and my home. if for some reason one of these machines dies due
to hardware failure and i want to get stuff off the drives, i put the disk
containing the /home partition on the failed machine into a working
machine and reboot. What /home gets mounted then? the original /home or
the new one from the dead machine? (and don't say end users wouldn't
possibly do that... if they are adding hardware into their systems this is
by no means beyond their capabilities)

at least with physical device nodes i can say 'computer, you will mount
this partition on this mountpoint!' and be done with it.

so tell me then, how would one discern between two partitions with the
same label?

just a thought

If you think that a stream of APIC retries is 'working very well,' then
I'm sorry to say, you've got another thing coming. :p Besides, a 40 day
uptime is *not* all that spectacular; I've had uptimes in excess of 200

anyways, the fact remains that it was your motherboard that is causing

kernel didn't catch these errors is because (IIRC) it wasn't looking for
them; they were there even then. The BP6 is a low-end mainboard and was
engineered very poorly; these errors are due to that fact alone.

Talk to you later,

It looks like you've been r00ted, dude!

Someone installed a r00tk1t and you are now seeing the after-effects of
it. What I'd do, in your case:

back up /usr/local, /home, /etc, then reload the system clean, and replace
teh backups. The system should be in a close state (read: no root kit) to
before you reloaded it.

Good luck!

Just to add some input and insight on here, I loaded the system down with
some FFT algorithms, and then ran an 8-way kernel compile. The machine in
question is a dual P3/600 with 512MB RAM, 2.4.0-test11. The load
skyrocketed to a mere 13.6. xmms was still running, didn't skip even
once. The FFT algorithms didn't bitch at all. Neither did the kernel
compile. In fact, it compiled without a hitch...

I dunno what to say about these boxes that segfault all the
time... Probably just bad hardware somewhere along the lines.

What's funny, is that this actually executes on SPARC hardware, but
immediately segfaults. On Intel hardware though, you get a message similar
to:

zsh: illegal hardware instruction (core dumped)  a.out

I wrote relatively the same program in college. It exploits the F0 0F bug
found in early Pentium hardware.

You are wrong: If you modify the kernel you have to make it available for
anyone who wishes to use it; that's also in the GPL. You can't add stuff
to it and then not distribute it, that's in violation.

It's somewhat comforting to know that someone else has the same problem as
I do. I'd be willing to bet that he's using SCSI hostadapter emulation
with this. I am, and it only started happening as soon as I enabled
it. Any ideas? I need the sg stuff for my CD recorder to work properly...

Why bother fixing it? It's too bloated and stupid in the first
place...That's why we run Linux.
Anyways, this is really causing too much clutter for this list.

Apparently Linus doesn't like the way it handles interrupts or something,

aaaah! complete lockup 2.4.0-test9 SPARC32

2000-10-04 Thread Dr. Kelsey Hudson

I just had my box completely lock up under 2.4.0-test9. I had insmodded
the dbri.o audio driver, which for some reason was refusing to work, at
all. So I rmmodded it, and at that point, the screen flickered once and
wham, complete lockup, nothing responds at all, no network, no SysRQ,
anything...Not even an oops printed to the screen.

Machine:
SPARCstation 20, 1xTMS390Z55 50MHz SuperSPARC II w/1MB SuperCACHE
48MB RAM, about 9G total disk space spanned over 3 drives, TGX...

Lemme know if you need more info.

Of course it does. When I compiled it before I didn't have PCI support on
either, but it tried to compile it anyways, and barfed and died. It no
longer barfs and dies, so yes, it is fixed. :)

Let me try this and find out...

Hmm. I get an error when trying to run 'make xconfig':

gmake[1]: Entering directory `/usr/src/linux-2.4.0-test9/scripts'   
cat header.tk >> ./kconfig.tk   
./tkparse < ../arch/sparc/config.in >> kconfig.tk   
-: 97: unknown command  
gmake[1]: *** [kconfig.tk] Error 1  

OK, Big deal. I'll use menuconfig.
That seems to work...

making dep...

::curses his SS20 for being so SLOW!::
I need better than a 50MHz processor in this damn thing. :) Better yet, I
need a better machine! :) Got any donations? Just kidding.

...Ok...Making boot...

Damn. A good 2 hours later and it looks as though the compile exited
cleanly :) yaaay! 

The answer to your question is yes, the fix Linus put in today fixed the
problem :)

Talk to you later,
