Bug still exists in Fedora 16 I have had the same errors and screen blanking, but under different tasks. My T520 would go blank and not recover sometimes just sitting idle, and sometimes during flash video viewing. I have been testing the following kernel option with success. video=LVDS-1:e I came across this info in the following bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/515246/comments/55 Bug persists with kernel 3.3 Error persists in Fedora 17 as well... Is this something that can be fixed? I have a similar problem with Centos 6.3, running console only. kernel 2.6.32-279.5.1.el6.x86_64 mobo ASUS P8Z68-M PRO KVM DLink DKVM-8E Monitor SAMSUNG SyncMaster 793mb if I attach the KVM to the PC, the monitor begin to turn on/off every a few seconds and get lots of [drm:pch_irq_handler] *ERROR* PCH poison interrupt here a patch for kernel 3.5 https://lkml.org/lkml/2012/6/8/530 https://bugs.freedesktop.org/show_bug.cgi?id=50501 the following kernel option solve my problem. i915.modeset=0 Thanks Alejandro, Your kernel config option helped my system stay stable too. Should be fixed in 3.5 with:

drm/i915: pch_irq_handler -> {ibx, cpt}_irq_handler
Cougar/Panther Point redefine the bits in SDEIIR pretty completely.
This function is just debugging, but if we're debugging we probably want
to be told accurate things instead of lies.
I'm told Lynx Point changes this yet more, but I have no idea how...
Note from Eugeni's review:
"For the record and for future enabling efforts, for LPT, bits 28-31
and 1-14 are gone since CPT/PPT (e.g., those must be zero). And there
is the bit 15 as a new addition, but we are not using it yet and
probably won't be using in foreseeable future."

Still doesn't work for me, with kernel 3.5.3 Not even with the i915.modeset=0 setting on boot. |
