Subject: Suspend regression with 2.6.29-rc

Hi,

with 2.6.28, I have sporadic suspend failures with suspend to RAM on my
Mac mini core duo (Intel Core Duo, i945 chipset and graphics).  I
traced it down to the DRM driver: without X and DRM unloaded, I had
more than 200 suspens in a row without any failure.

With 2.6.29-rc6-00029-gf7e603a, even with DRM unloaded the computer
hangs at suspend time after some attempts.  I also tried other
2.6.29-rc kernels, and all had unstable suspend behaviour.  I can't
give any further details, as the console is dark and I have no serial
console.  Any hints what I might try except for bisecting?

Regards,
Tino
