Same as c_t:
Samsung X20 XVM 1730 V
After uspend to ram the screen is black (turned off, same result with X running and "recovery mode" without X), some times the pc awakes later.
None of the suggested things worked
With the kernel parameter "acpi_sleep=s3_bios" the display remained black (turned on) but the pc freezed.
Resume works with feisty's kernel one time, the second time without reboot, the hard disk is dead (rejecting scsi io to dead device), but that seems to be a different bug.
