What is the state of the drive when you powerdown/unplug?  Is there
currently a disk mounted on the drive?  Do you have hotplug/coldplug

[gentoo-user] System crash when switching off an usb2 dvd writer, help !

2005-01-13 Thread Gael Beaudoin
I have an external dvdwriter (nec 3500a) in a 3,5" usb2 external rack.

It works flawlessly : I can burn cd/dvd without any problems.

But when I switch it off, or unplug it, gentoo freezes : when under kde, the 
programs stops responding, and after few seconds, the mouse stop moving too.

There's nothing in /var/log/kernel, and I don't know what to do.
I have an up to date gentoo, using 2.6.9 kernel.

Any ideas ?
Thanks !

Not quite so, as it will not utilize anything save jumps. Jumps won't
generate much heat in any CPU, altough ps will show 100% CPU usage. If
you really want to test for heat, install GIMPS Mersenne client from
www.mersenne.org (no Gentoo package available). You can set the client
for system benchmarking only, if you're not interested in joining the
prime searching project.

Note that some errors, like memory errors, can take a long time to be
noticed. Leave the client running for at least a week to see if your
memory is OK. GIMPS can detect memory errors which are unnoticed by
memtest86 binary.

Seems like a lot of work... if you just want to peg your CPU for a heat

I have just had exactly the same problem with a new PC I built for my other
half, would work (in windows) fine until at some random interval it would
just freeze rock solid.

Suspected heat, memory, gfx card, etc (after 3 days) it turned out the be
the PSU only providing just enough juice and a small fluctuation was enough
to kill it.

This is of course no help to you on a laptop :|

One easy way to rule out over-heating, install povray and leave it rendering
something overnight (at a command prompt, not in X), its still up in the
morning (btw, doesn't have to be pov, anything that pegs the cpu at 100%

of it)

RE: [gentoo-user] System crash

Just a thought, but you said it was a compaq laptop. I have a compaq laptop
of a similar vintage, and it uses the ATI IGP Radeon chipset. I haven't
updated it for a while, but I got a lot of random system freezes caused by
the IGP south/north (can't remember which one is which, i'm not that techie)
not being supported by the kernel. It does it's best, but fails occasionally
and apparently at random (random crashes never are random, they just appear
that way). That is on 2.4.X series kernels. There may be support for it now
though.

I just (I think) fixed the exact same problem on my computer.  It's been
running for several days now without a problem.  Previously, Mozilla would
suddenly crash, licq would crash rather quickly if I attempted to talk
with it, X would suddenly crash (I'm looking at a console), the computer
becomes unresponsive to keyboard and mouse, or the computer would
spontaneously reboot.

So, having removed the bad RAM, it only has 256MB instead of 512MB, but it
doesn't crash.  (It still did though when I removed the wrong one, leaving
the defective one in.)

Try running "glxgears" on it. If that crashes it it's most likely an 
opengl problem. Is it a VIA chipset?

BTW: can the problem become from my video card  (ATI Radeon 7500) 
(Driver: radeon) ?

Because I remember before 1 year one I was using the driver VESA .

and I just saw http://www.bityard.com/article.php?sid=443 :

It's also worth mentioning that the support for the ATI Radeon chipset, 
while fairly complete, is also very new (as of XFree 4.20) and not as 
stable as I'd like. I've seen X crash out for no obvious reason twice in 
the last week. There are also little drawing glitches now and then. 
Hopefully all of this will improve as the driver matures. Meanwhile, I 
can live with it.

I will do it and tell you the result.

I don't think the problem from CPU overheat for 2 reasons :

1- I Allways keep my laptop near to the air conditioner.
2- I have a script that check the CPU temp. every minute and if it over 
70c it will shutdown the system.

Yep, that sounds about right.  When the processor overheats, it can't
handle interrupts anymore (kybd, mouse), but the video card continues to
display the last image presented.  It was a few years ago, but that
sounds like exactly what was happening to me.  

Next time it happens, reboot into bios settings and look around for the
sensor readings.  See what the cpu temp is.  

You also may want to look into lmsensors, it will report sensor readings
while in linux.  

There is still the possibility it could be something else, but since it
happened on three different distros under different circumstances, I'm
going to lean towards processor overheat. 

Good luck with this one, hardware errors are a b*tch, and usually end up
costing money, especially on laptops.  I sincerely hope it's something
else...

Cooper.

I was RedHat and Mandrake user and now I am (I hope for ever :) ) Gentoo 
user

but I have a big problem. linux sometime crash (hang) sometime without 
any reason !!!

This happened to me in Redhat,Mandrake and now in gentoo

sometime I don't do anything , just browsing the net with mozilla !!!

anyone know any reason for this crash ??

My PC is :
Compaq Presario 2800 (Laptop)
HardDisk 20GB
Memory: 256M
CPU : Intel Mobile 1400


I would suspect hardware.  Listen for the fan, does it stop?  Is it
running at all?  I once had a Cyrix :( 266MHz that did it all the time,
regardless of Linux OS or configuration.  It was overheating.

BTW : How can I make gentoo allway check the hardisk (ReiserFS) if the 
shutdown not clear



ReiserFS is a journalling filesystem, in *theory* it won't loose data
during a crash.  I'm not sure how to force the check on reiser, but
adding 'reiserfsck /dev/hda?' to rc.local wouldn't hurt.  Just slows down
bootup times a little.
HTH,

Cooper.
