--- Comment #72 from tomas m <[email protected]>  2010-08-08 21:03:39 ---
ive hit a similar hang twice since using acpi_sleep=nonvs.

out of hundreds of suspends/resume cycles. the system would not come back from
suspend. (it tries to, but screen stays black, and alt-sysrq will not work)
just like it did when i first posted the bug.

could there be a race condition somewhere we are missing which is being
triggered by nvs saves? and hardly unlikely without the saves? 

is there any way i could test this out? for example, instead of restoring the
nvs states, simply delay a bit and see if it hangs that way? 

how could i implement such a delay?


thanks
