[Bug 610716] [NEW] incredibly slow resu,e from suspend

[cutterjohn]

Public bug reported:

Resumes from suspend are taking 3m or more to get the unlock dialog,
disk access is going NUTS during this time AND ater unlocking the
machine.

It is simply faster to ALT-SYSRQ+RSEINUB than to wait.

This did NOT occur for me with 9.10(dist upgrade) or 9.4(org install alt
boot since OSS drivers phail w/my GPU ATTM) w/EXT3 & original
GRUB(shouldn't matter) but w/10.4 I did a FRESH install
grub2/ext4/proprietary GPU drivers(catalyst 10.6).

No process on getting a useable term is using anything crazy as far as
CPU tme goes, however excessive disk access slows the entire system to
near unuseability even for several minutes after wasting 3m to unlock it
in the first place.  VM usage can be 0 or gigabytes, still same
EXCESSIVELY pokey resume times.
