Hi,

just to add my experience. Maybe it helps. I haven't been able to get
swsusp working on any 2.4.x kernel until i did an
    hdparm -u1 /dev/hda
now the strange thing: I tried to turn on the frame buffer device and
it started chrashing again until i did
    hdparm -u0 /dev/hda
Before I tried using suspend in 2.5.x with varying success. Now
everything runs like a charm. Without unmask irq's first the kernel
dumped
with either a kernel BUG statement or a fault in ide-disk.c

hope it helps, regards

Troels Haugboelle

PS. I am running on fujitsu lifebook P4-M laptop with reiserfs and intel
845 chipset.
I have only one hard disk too.
