Some problem with nouveau

["Éric Brunet" <Eric.Brunet@lps.ens.fr>]

Hello,

I have HP Z400 desktop computer running in x86_64 mode with a fedora 12
installed on it. The computer has an nvidia (NV96) card, for which I am
using the nouveau driver.

Everything (meaning 2D acceleration) was working fine up to
kernel-2.6.31.12-174.2.22, and when fedora updated to 2.6.32.xxx (now
kernel-2.6.32.11-99) it stopped working. I also tried a vanilla 2.6.33.3
and it doesn't work either (I wouldn't dream bothering LKML without trying
a vanilla kernel...) Here are the symptoms:
  when X is launched, the computer reboots instantaneously to the BIOS
  greeting screen, leaving the computer in such a state that the BIOS is
  enable to work (it never reaches grub, but keeps on rebooting after a few
  seconds). Shutting down the computer is necessary to recover. I have no
  useful log as the buffer have not been flushed: /var/log/Xorg.0.log is
  found empty on the next reboot.

I filled a bug with fedora with more info (dmesg, lspci) on
  https://bugzilla.redhat.com/show_bug.cgi?id=578108
but I had zero response.

So to sum up:
        2.6.31.12 + fedora patches      is working
        2.6.32.xx + fedora patches      is crashing horribly
        2.6.33.xx vanilla               is crashing in the same way.

Does that count as a regression ? I am a little bit at a loss as how to
provide debugging information on that one.

Thanks,
