Comment 4 Florian Mickler 2010-02-08 10:11:01 UTC

hey, this is the oldest tracked regression currently... as such (and as a bisected one, which got reported 2 times) it deserves some action... dosn't it?

Comment 5 Rafael J. Wysocki 2011-01-16 22:03:43 UTC

Well, I'd say, having looked at this issue, the problem only happens if
suspend is carried out with no_console_suspend, which isn't guaranteed
to be reliable at all.
