           Summary: suspend-to-ram problem on GF7600 notebook
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: mjt at tls.msk.ru
         QAContact: xorg-team at lists.x.org


I've sent this bugreport to the mailinglist, but apparently the post produced
no interest whatsoever.  So re-submitting it here.

Full details are at
http://lists.freedesktop.org/archives/nouveau/2010-August/006238.html , dmesg
from the bootup are here:

.

In summary, current KMS driver in kernel does not work in suspend-to-ram-resume
cycle, leaving the screen non-functional after resume, at least on a particular
notebook, and generating tons of kernel messages.  There's no X involved at all
(I tried to suspend/resume without starting X), but from X the behavour is the
same.

I selected x86(IA32) arch, but exactly the same happens with 64bit kernel.

Thanks!
