I copied this message from the dmesg listing. From time to time I have
seen this BUG for swapper, events and kjournald. Now that I have some
time, I thought I would attempt to see if there is a fix available or
try to get some information that I can use to debug this.
Questions?
How do I determine is a fix has already addressed this issue.
If no fix is available, how do I get additional data and submit this as
a bug?
