Most recent kernel where this bug did not occur:
Distribution: Debian testing
Hardware Environment: IBM T60p
Software Environment: SATA set to Compatibility in BIOS (ata-piix)
If I echo mem > /sys/power/state, the machine suspends fine. If I suspend in a
console, there is no display. If X was also running, switching to F7 brings up
X and I can then switch back to one of the virtual terminal consoles.
After doing this, consoles 1-4 are white, but can be cleared, and otherwise
operate normally again.
Steps to reproduce:
Suspend to mem while in a virtual terminal console, then resume.
S3 video restore is not an ACPI feature, it is a BIOS and video
Verify that you've got the latest BIOS for the box,
and then check that you've got the latest ATI drivers
in Linux and in X.
I have the latest BIOS (1.09) and the latest ATI fglrx (8.27.10)
I don't think fglrx has anything to do with this, though. I made sure I tested
without the ATI kernel driver to avoid taint issues and the console is still
black, except I can't recover since X isn't running.
I'm also a bit confused. I thought with ACPI that suspend modes were handled by
the kernel, not the BIOS.
