Finally, it came down to what seemed like just one error message while resuming: kernel: MCE: The hardware reports a non fatal, correctable incident occurred on CPU 0 So I booted up with the "nomce" option and the acpi option you had below and now the MCE error does not show up while resuming.. but I still don't have display after resume. > 1) display reinit: if acpi_sleep=s3_{bios,mode} at boot doesn't help, I > don't know what does, > 2) keyboard / mouse (touchpad) dead: apply the patches found here [1] > against a vanilla 2.6.0, should fix it once and for all, Hopefull I'll get to the point where the only things that don't work on resume are the keyboard/mouse. > 3) uhci-hcd's appalling PM / suspend / resume support -- a workaround is to > unload all USB drivers prior to suspend.

This definitely seems to be the issue.. wonder if this will help but here's the output on resume (and the last line from suspend) from syslog: Dec 24 19:51:01 variance kernel: hwsleep-0257 [33] acpi_enter_sleep_state: Entering sleep state [S3] Dec 24 19:51:01 variance kernel: Back to C!
