Subject: [2.6.28-rc2 regression] hangs on wakeup from s2ram

Dear all,

my macbook pro 1,1 suspends nicely (s2ram) but on wakeup I see a black
screen...

Does anyone else observe this? As this was from within X (and it still
works in .27) I cannot give more details without further investigations
from the cmdline...

Most distros switch to a console and even after that do suspend (if not, just
try it from console). Do you see any traces when you add no_console_suspend to
the kernel command line?

This is also happening with my Vaio, and 2.6.27 works fine suspending
to RAM from inside X.

I was silent about this issue (it happened before -rc1) because I really
did not have the time to bisect it, which I think is the best way to
solve this issues quickly.

I will try to bisect it in the next days, but I can't promiss anything.

I still have this hang in resume -rc3+git current, but I don't have the
time to dig into this for the next 3 weeks :(
