Thanks for looking into this. It's the same behavior w/ and w/o Xorg. At the
STR
process the backlight goes off shortly but remains lit during suspend. The
screen
goes black and stays black when out of suspend. Some flickering on/off when
entering and leaving STR. There's short harddrive activity when coming out of
suspend. Also, suspend- and power-led blink/lit as they are supposed to. The
box
is then locked up, not reacting to keyboard input or even sysrq. Hard power off
required.
I've seen it coming back out of suspend halfway sane (post on lkml) but that
hardly ever happens. The only known workaround for me is to go with nomodeset
(and loose 3d acceleration as well).
