Description Dave Hodgins 2011-09-09 20:23:27 CEST 
When I first checked my system today, there was a kernel call trace on the
screen.

The precesses running included kde with the clock screen saver, boinc, and
at the time of the crash, mgaapplet.

The only messages in /var/log/messages were ...

When mgaapplet checks for updates, it's normally less than 1 minute.

I've been running 2.6.38.8-server-5.mga since Sept. 1st.  This is the first
problem I've seen.

I don't know if this can be recreated, or what "Bad page state" means,
but thought it should be reported.  May be my 6+ year old hardware is
starting to die.
Comment 1 Thomas Backlund 2011-09-09 23:20:57 CEST 
Can you run memtest on that system to rule out hw

and please run it for a long time, for example over night...

Comment 2 Dave Hodgins 2011-09-11 02:56:32 CEST 
I ran memtest for 14 hours with no errors detected, so it seems more likely
to be a kernel problem, although I have no idea how to recreate it, as it
happened while I was away from the system, and has only happened once in
8 days of using this kernel.
Comment 3 Manuel Hiebel 2011-10-29 16:04:28 CEST 
Is the bug still valid with the two updates (one in testing) ?
Comment 4 Dave Hodgins 2011-10-30 06:48:44 CET 
Yes, but superseded by bug 3186.  Closing as old.

Status: NEW => RESOLVED
Resolution: (none) => OLD
