this annoying, i need to reboot my X61 Thinkpad every hour :(

Comment 4 Ludwig Nussel 2012-07-10 15:07:07 UTC

same here

I need:
a. the device ID of the GFX chip (second line of lspci -n)
b. the machine itself to debug this.

Did this work with an earlier version of the kernel? If it did bisecting would probably be the best chance to find the origin.
Intel hardware has the tendency to hang only the latest can reliably be reset to a state to make it work again. I have numerous bugs with this across almost all gens of hardware.

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)

00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (secondary) (rev 0c)

lspci -n
00:02.0 0300: 8086:2a02 (rev 0c)
00:02.1 0380: 8086:2a03 (rev 0c)


b. its my Lenovo ThinkPad X61 laptop ... how do you need the machine? ;)

I had openSUSE 11.3 before which worked fine and then installed 12.2 Beta 2... Did not have any intermediate kernels.

This is GEN4 hardware. Not really the very latest.

I'm not sure if I even want it ;) - I have 'nough SLES issues to look at.

It is not even clear that this is triggered due to a kernel change. Something else in the desktop may have changed which is triggering this issue. It'd be important to break down which application is triggering this.
I've just installed a box to investigate the same issue on GEN2 hardware.
I may be able to dig up some GEN4 hardware and could try to reproduce this there.

This is very likely an dup of #768584.
