Unfortunately, it seems that this happens with the performance CPU
governor (after disabling the ondemand with that update-rc.d script).
The only difference, that the laptop become hot, and the ventilator
never stops - so the performance cpu frequence governor is working, I'm
sure). And firefox
Yes, it's Natty. I'm not totally sure that this is only hardware problem - I
had this problem for a couple of releases, since the fglrx driver stopped
supporting my pretty old graphic card, so I though this is a deficiency of the
open source driver. As there is nothing in the log files, after
Unfortunately for me this bug is happens pretty frequently - with a graphics

@Zsombor: it really is a hardware problem. You have to turn off AMD's
Cool and quiet feature that slows down the CPU when it's idle to
reduce power consumption. It looks like there is a real problem with the
onboard graphics card when the CPU speeds back up again. I was getting

Leann, how about also closing this bug for source-2.6.15, since you
closed it for 2.6.20? Five years on, I would actually prefer to see this
bug closed to having it clog my bug list. It's not a kernel bug anyways,
but a faulty hardware design by Shuttle computers.

Hi There
I have posted a workaround here:
I am thrilled to find an answer to this issue. I'm on an AMD Athlon 64
3200+ with a built in ATI card. I have tried every ATI driver/config
combo under the sun to no avail.
I am willing to try this out and help you test. I am on 7.10 right now.
I reinstalled from 8.04 in hopes to fix this. It
Sorry...need to clarify.
I will try the kernel upgrade, I can't afford to run an Alpha on this
box.
Where would I find the Kernel package?
Thanks,

This is still an issue with Gutsy and Hardy.
The workaround still applies. I am concerned that a lot of new users
will be put off because of this and other driver related
issues..Like with Gutsy the boot CD - X works in 640x480 mode. In
Hardy, X is broken and you need to boot up in failsafe
This bug has had no activity for a considerable period. This is a check to see
if there is still interest in investigating this bug report.
Is this still an issue against Gutsy and/or Hardy ?
If so, does above mentioned workaround still apply?

I used sysv-rc-conf and disabled powernowd. This solved the problem, I
haven't had a crash since then.

I hadn't known about that tool. Neat. Glad you're system is back to
being stable. I know how good it felt for me.

Hi
I have the same issue with Feisty (7.04) wih kernel 2.6.20 and all
updates installed.
System freezes to a white screen a few minutes after launch of Firefox
(also up-to-date). The only recovery option is a hard reset. I have not
looked at logs to see what happened in the kernel.
Disabling
Are you positive chmod disabled it? I believe powermod may be sourced
in /etc/init.d/powernowd.early, which does not require the file to be
executable. This is what I did in my powernowd instead:
--- /etc/init.d/powernowd 2007/05/09 06:32:08 1.3
+++ /etc/init.d/powernowd
Just to clarify: if you disable powernowd, you no longer
see the hangs, is that correct?
That's correct. I haven't had a hang since I turned it off, which is at
least three weeks of almost daily use now.

I think I may have found the cause: enabling AMD CoolQuiet (powernowd)
when the internal graphics card is used. (Why Shuttle would design an
AMD-based motherboard with an IGP that crashes when these two features
are actually used? Good question.)
I said above that I never saw this crash in
The problem is still there with up-to-date 6.06 LTS and a 2.6.15-27

because some of the libraries I need come only in 32 bits, and the

hour, especially once I
