[Bug 561292] Re: Resume from sleep fails / extremely slow with fglrx

[Johannes H. Jensen]

Suspended my computer to RAM yesterday with 1818 MB free system memory
(of the total 3962 MB) and 181 MB swap used. That should be plenty of
room for the 1024 MB video memory from my graphics card, right..?

Resumed it now and free reports 2382 MB free memory and 560 MB used
swap. I/O is still very heavy now, 5 minutes after the resume with disk
reads reported by iotop up to 2.5 MB/s by various processes - firefox,
X, gnome-panel. Comparing with my laptop which has no disk reads
whatsoever, this behavior seems far from normal to me...

So it doesn't seem like it's swapping at all - system memory is kept at
a constant level. What I do notice, however, is that none of the system
memory is used as buffers/cache. Could it be that for some reason cache
has been disabled after resume which causes processes to constantly read
from the disks?
