Reporter has tested upstream v2.6.38-rc4 and that is also bad. Will bisect with reporter.

I am seeing the exact same behavior on the t410 running linux-image-2.6.38-3-generic from the kernel ppa.

Almost the same thing happens on my Dell Latitude E6510 using vanilla-sources 2.6.38-rc4. Surprisingly, the regression was introduced with rc4 because I had rc3 earlier and resume from suspend worked, sort of (the screen stayed dim, so I had to hit Fn-Auto (left arrow) to get the screen to show fully lit).

The difference for me is that the laptop is hard locked on resume. I can't ssh or sysrq. I can only do hard shutdown by long pressing the power.

I did a pm_trace against the v2.6.38-rc4 mainline build on my T410 and got the following in dmesg:

Magic number: 0:117:321
hash matches /home/kernel-ppa/COD/linux/drivers/base/power/main.c:514
tty tty46: hash matches
pci 0000:00:02.0: hash matches

/sys/power/pm_trace_dev_match contained:

tty
i915

I'll try to debug some more later this weekend.

drm/i915: Reset crtc after resume

Based on a patch by Takashi Iwai.

    Tested-by: Takashi Iwai <email address hidden>

I haven't gotten the time yet to find exactly where the kernel is actually hanging. The changes can only be indirectly causing the hang, as all it really does is introduce the resetting of some values into the resume path.

Same problem with 2.6.38-3 from xedgers PPA on Maverick and Lenovo x201t. 2.6.38-2 works just fine.

The following commit in v2.6.38-rc5 fixes this regression in my testing (about a dozen S3 cycles).
