Hi,
I was testing yesterday release of kernel, and I have had a lot of
problem with the new kernel. It boots ok, the first time it
suspend/resume ok, and then at the second or third attempt to suspend,
the suspend process will not go though (I suspend using s2ram -f
-p -m); it will just lock the screen (I think that's in Ubuntu
scripts) and nothing more. Coming back, there is a message of
the style "DBUS locked up, but recovered" (if you need more
precise information tell me and I'll do my best).
After that, sometime there are processes that go to D state forever... one
sure form os triggering it here is to try to do "sudo something". At this
point, no new windows opens in gnome; switching to a VT works, and I can
start a shutdown, but it locks saying something on the line "soft lockup on
CPU#0 detected, 11 seconds stall" forever. I need to d a SysRq-B to restart.
I got a track of locked processes with SysRq-T. The common denominator
is __mutex_lock_slowpath() here. I do not know if the system fails to
suspend given that problem or the other way around.
2.6.23 worked like a charm. The system is a toshiba laptop
A305-S5077, sata disk, pretty standard I think.
Greetings,
Romano
