This entry is being used for tracking a regression from 2.6.28.  Please don't
close it until the problem is fixed in the mainline.

ping Tino. :)
Comment 3 Tino Keitel 2009-03-19 00:15:50 UTC
I tried 2.6.29-rc8-00223-ga1e4ee2 without success. With X running, the computer hangs during suspend. Without X and init=/bin/sh, the text console is black after resume, so I can't get anyting usable with 2.6.29-rc.
Comment 4 Tino Keitel 2009-03-24 13:09:01 UTC
I tested the 2.6.29 release and saw the following:

- with KMS enabled and X running, the kernel hangs at suspend

- with a .config from 2.6.27 and being conservative in make oldconfig (and so keeping KMS disabled), suspend worked at least 2 times in a row with X running
Comment 5 Rafael J. Wysocki 2009-03-28 21:29:31 UTC
In fact suspend-resume is not guaranteed to work with KMS enabled, as far as I can say.

So, if it works with KMS disabled, I'm closing the bug.
