1. What was the date of your previous sources (the working ones)?
2. What scheduler are you running with, have you tried the other
one?
3. Is DDB, INVARIANTS, and/or WITNESS compiled into your kernel?
4. Any particular/interesting boot-time tunables or sysctl
settings?
5. Can you reproduce without Mozilla in X?
6. Do you have serial console, if so can you get anything once
the seeming "lockup" occurs? (it may not be a lockup, you
might just not be able to see anything because of X dying).
7. Can you turn off ACPI and see if the problem goes away?
8. Can you backout the preemption change (jhb a few days ago)
and see if the problem goes away?
Basically, there are a number of things you can do to further
help analyze the problem.
