[gentoo-dev] System hangup w/ X taking 100% cpu

[gentoo-dev] System hangup w/ X taking 100% cpu

[Dan Armak]

Hi all,

On my new r12 system I've had a hangup in X11. No apparent cause. The system 
stopped accepting any input and the screen didn't even complete a redraw. The 
mouse went on moving as it was in h/w, but clicks were no good. Magic sysrq 
wasn't responding either.

I logged in via ssh, and top showed X was taking 100% cpu. I tried killall X, 
no effect. I tried kill -9 <X pid>, the remote login hung up and i couldn't 
ssh to it again. I had to do a hard reboot.

Then I expirienced the same effect twice on an old rc5 system which underwent 
absolutely no updates or config changes for a few months now. Only this was 
standalone not on a net, so I couldn't login via ssh.

Both rc6 lockups were when running kmail, both rc5 lockups while running 
ksirc.

Trying to send this message, I had another lockup on the rc6 system, hope 
this reaches you.

I'm absolutely mystified. Ideas? Anyone seen this kind of thing before?

To add to this my really old -rc6 system I believe has similar problems - konqueror locks fairly frequently when dragging and dropping (when using as a file manager) - I never ssh'd in to check top because i don't like having any open ports on my laptop. If i ever get my brand-new gentoo install to work with PCMCIA correctly i'll report on that. I do not have this issue with Nautulus or GMC (however i do have a problem that sometmes i get stuck with the "drag and drop" mouse pointer and have to switch to another console to kill -9 gmc or nautulus - i assume that is a backbox or xmms issue). I use default optimization flags for PII in make.conf.

For anyone who is curious this is a Thinkpad 600e / 128mb ram / 366mhz PII / NeoMAGIC video / ambicom ethernet / CS4232 audio w/ oss drivers. W2K did really odd things to the IRQ/DMA assignments but i reflashed the bios and used mkfs to fix that problem :)

PS: I'm saying this in hopes that it will help diagnose the problem - I don't really expect to be able to look at much for the next week as it's finals time :( Over xmass break i do plant to get this darn thing workin right :)

just in case this is really, really H/W related, i think i'm gonna
checkout "tux" or something ... a distro made "just for" laptops ...
maybe they have some tricks with these little gizmos...

I've had a 3rd lockup right after sending this off and  am now working on the 
rc5 machine again. The rc6 one worked perfetcly OK for 2 days then I've had 3 
lockups in 20 minutes right after it (a laptop) returned from the lab from 
"repairs" of its mouse. I'll be investigating that, but the rc5 hangups are 
in any case a mystery so please help me with any ideas.

this is abviously a hardware problem, if you want help, we need to get
all the specs on your machines (the sick ones) : CPU, RAM MB ...
intel/amd speed NIC VideoCard.... etc

Toshiba Satellite 3000-400 which includes:
CPU: mobile p3-900
RAM: 256MB
network: 8139too driver (forget the name of the card) (builtin - mini-pci)
Video: nVidia GeForce2Go 16MB RAM with the latest drivers from portage

Nothing in this or anything else seems very helpful, because it worked before.

Re: [gentoo-dev] System hangup w/ X taking 100% cpu

[Dan Armak]

It seems this may have something to do with using an external CRT with the 
laptop. It hangs up whenever I try to switch betwen the CRT and the laptop's 
builtin screen. I can't elaborate right now, as I have to go, be back soon. 
Hope that sparcs up some ideas. I may try to downgrade my nvidia driver. Also 
I should start my console in 1024x768 again - haven't set that up yet.

Hi Dan

What version kernel, nvidia driver and filesystem are you
running?

I updated my nvidia drivers to the latest 2313, and only had
problems (screen corruption, lockups, etc) on a system that
had been running stable for a long time now. i went back to
the previous version, and it is 100% again.  I also had problems with my
old savage and sertain drivers.

Then, nearly a year back, I had the same type of problems
(lockups), but this was due to bad ram, and a kernel/reiserfs
and hardware compat problem.

I have kernel 2.4.16 w/ the std patches from portage, nvidia 2314 and 
reiserfs.

Things now seem to have stablizied somewhat after I turned on a 1024x768x16M 
vesa framebuffer for the console. Now it only hangs like that when I press 
Fn+F5, the hotkey for switching between the builtin and external screeens. 
Still I wouldn't call it completely stable.

But I've just found out another possible cause; I compiled agpgart into the 
kernel instead of as a module, and now I can't use NVAGP althuogh I want to. 
So I'll switch that and see if it helps.

Well, it didn't help. I may be that the 2.4.14->2.4.16 kernel upgrade is 
causing this. In any case, I'm now starting an rc5->rc6 pugrade of my nat 
router/gateway box, and won't be online for a day or two. Hopefully this'll 
be resolved by then.

The same kind of lookups happened to me in my debian box.
I believe that the problem is related with the nvidia drivers, i also use
the latest nvidia driver.

Re: [gentoo-dev] System hangup w/ X taking 100% cpu

[Dan Armak]

Well, to close this, things seem to have stabilized more or less. The only 
thing that hangs the system without fail is swtching via the Fn+F5 hotkey 
between the builin and external monitors.

I'll try to downgrade the kernel to 2.4.14 later and see if that helps, or I 
may just wait for 2.4.17 (which has lots of fixes I need in 2 drivers) and 
see if that works.

Thanks, everyone, for your help.
