After an S4 ACPI suspend, my system has panicked on resume in ata_dmastart.=
=20
The system is normally capable of resuming just peachily, and I haven't=20
updated the kernel or world in the past few days and it's worked fine until=
=20
just now. :-)
I'm -not- using my ata-suspend patch to ata-disk.c, just to rule that out u=
p=20
front. :-)
I'm updating my sources to see if I can reproduce the bug with HEAD. In th=
e=20
meantime, I hope this information proves useful to someone.
