--- Comment #27 from Ronald <ronald645 at gmail.com> ---
Just tested v3.8-rc1 + nouveau @ 'drm/nouveau/fan: handle the cases where we
are outside of the linear zone' on this FX5200.

Especially 'drm/nouveau/bios: cache ramcfg strap on later chipsets' looked
promising (even though I don't have a recent chipset... there was hope...).

Things did not regress further. First suspend works most of the time, second
suspend crashes. Symptoms did change a bit. When resume eventually completes, I
do not see a frozen/unresponsive desktop but the screen goes black with
red/green (I don't think i saw any blue) pixels scattered all over it. Density
was really low, so maybe 200 pixels on the entire screen? These pixels did not
move or alterate or anything, it was pretty static and boring actually.

But I recommend Michael and francoism to test latest HEAD as the mentioned
commit might fix your issue's???

I will add a dmesg from v3.8rc1 kernel for your viewing convenience. This is a
dmesg from syslog, not from the 'dmesg' command!
