Re: System slowdown/freeze

I demand that zeno may or may not have written...

Running Ubuntu 6.0.1 on an IBM ThinkCentre desktop machine.

PROBLEM: The display will frequently, (about once every other day) freeze
up; it seems to be on a random basis. I can invoke the consoles (ALT 1 -7)
but they take forever to respond...though I can't see anything in TOP that
indicates why this is. I end up doing: "~# shutdown -r now".

Something in the kernel, probably...

[snip; using Ubuntu]
The following is 'dmesg tail' after re-booting machine after it froze.

Quite possibly irrelevant.

dmesg output while it's in this "slow" state is more important; you might
also want to do Alt-SysRq-T to get some extra task info for bug reporting
purposes (booting with "log_buf_len=128k" may be helpful - "dmesg -s131072"
will grab the whole of the log buffer - though with any luck it'll all be in
/var/log/kern.log).

If you're using a proprietary graphics module, try again with an open-source
one (don't forget to reboot to get rid of the taint); if it stops happening,
it's almost certainly a problem with the taintware - forget trying to get
help from people here - you should talk to ATI or nVidia (as appropriate). If
it still happens anyway, well, you've just ruled out the taintware and can
proceed with trying to get help via Ubuntu's BTS, here, the kernel mailing
list... but Ubuntu's BTS should be your first port of call. (I'm assuming
that you're using an Ubuntu-supplied stock kernel.)
