Waking up from suspend regression

Waking up from suspend regression

[Michael Brennan]

Hi,

I am having some major problems with the newest kernels on my Thinkpad R61i 
and I'm doing my best trying to debug the problems.

One problem is waking up from suspend to RAM. Earlier kernels worked fine 
(e.g. 2.6.25), but with the latest the system is unusable after waking up.
When trying to wake the computer up it first is completely unresponsive with a 
black screen. After about 40 seconds it comes back alive and shows the locked 
screensaver. But whatever I do I just get error messages, trying to unlock 
the screen, it says authentication failed for some reason. If I try to log in 
from console I just get kernel messages about I/O errors from the SATA HDD.

I have bisected this and get this behavior after the patch: 
[ce6fce4295ba727b36fdc73040e444bd1aae64cd] PCI MSI: Don't disable MSIs if the 
mask bit isn't supported

I hope this is of any help at all.

Thanks

Same here, sata is dead after the resume. Thinkpad X60.

A week before -rc2, yet it isn't in... That's a bit sad, basically the
same story as -rc1 where wifi didn't work on my laptop. Oh well. THanks
for the hint Tejun!

Well, look at that.
I'm sorry I missed that bugreport, could have saved me quite a few 
recompilations. I'll try the patch, thanks.
