Thomas, on what hardware did you observe the regression?
Is a Intel mobile express gm45 chipset.
My machine has : 00:02.0 0300: 8086:2a42 (rev 07) 00:02.1 0380: 8086:2a43 (rev 07)
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
(Dell Vostro 1520, BIOS Revision A04)
Is it suspend or resume that is unreliable?
suspend never finishes/hangs.
and is randomly suffering from exactly the same problems...
So, I've applied your hint (in i915_drv.h), rebuilt a kernel, booted, and I've now successfully managed to go thru several suspend/resume cycles without having the machine hanging while suspend !
Will check in the long term, but so far, it's a win !
Thx, Paul
