    Dear folks,

    When I have upgraded several ports installed on my system using package,
    I have finally hit a bug which causes my firefox to stuck in "STOP"
    state, with 2 threads. When I attempt to attach gdb on the process, my
    laptop reboots instantly. Moreover, it is impossible to kill the
    firefox-bin process even with kill -9. When I go to single user mode
    with "kill -15 1", init will finally give me an "ps auxl advised"
    advise, with firefox-bin remaining.

    Is there anything I can provide to track down the issue, or is there
    some tricks that I can work on this issue by myself?

    The system is running fresh 6-CURRENT before
    <200505270607.j4R67LHU054037@repoman.freebsd.org> commit. My kernel is
    built with SCHED_ULE with FULL_PREEMPTION, PREEMPTION, WITESS,
    INVARIANTS, kdb, ddb built in, minus some hardware drivers that I don't
    use. More information available upon request.

    Thanks in advance!

    Cheers,
