Okay, I got video working on vanilla 2.6.16 by using "vbetool post" and
"vbetool vbestate restore" directly after "echo mem >/sys/power/state".
I copy all stuff need into tmpfs to ensure that it can restore the video
without hard disk access.
OOhh.. clever, wish I'd thought of that,
as all of my (now solved) suspend/resume issues
were *all* libata related.
when accessing hard disks first time after resume, I get (wrote it by
hand so maybe this is not 100% correct)
ata1: handling error / timeout
ata1: port reset p_ is 400000 is 0 pis 400000 cmd 8007
tf 80 ss 113 se 405000
ata1: status = 0x50 {DriveReady SeekComplete}
sda: current: senseKey 0x0 ASC 0x0 ASCQ 0x0
Sometimes there is "cmd 6" instead of "cmd 8007".
What to do, what to test?
Randy Dunlop's libata-acpi patch might work for you.
