Hi!
With 2.6.20, resuming from disk sometimes cannot returns on vt7 where X runs
but everything seems working, so just changing to vt1 and returning to vt7
solves the problem. But dmesg shows some BUG() output like [1] whenever this
problem occurs
I'm using 20070207 snapshot of suspend, s2disk is used to suspend2disk,
machine is a Sony Vaio FS-215B which is in the whitelist and works well with
2.6.16/17/18 (all have fbsplash and vesafb-tng patches [from gentoo]
applied).
[1] http://cekirdek.pardus.org.tr/~caglar/dmesg.2.6.20
Contact fbcon people... They are calling do_blank_screen+0x4e/0x218
from fbcon_event_notify+0x8f1/0xa1e ... probably without taking
neccessary locks.
Aha, it seems their blanking code triggers _while_ resuming, which is
not exactly nice.
Pavel
