ping Tino. :)
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.
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
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.
