Modified files:
sys/kern kern_ktr.c
Log:
- Don't bother taking a trace message if we have panic'd since doing so
can lead to further panics.
- Call getnanotime() instead of nanotime() for the timestamp. nanotime()
is more precise, but it also calls into the timer code, which results
in mutex operations on the i386 arch. If KTR_LOCK is turned on, then
ktr_tracepoint() recurses on itself until it exhausts the kernel stack.
Eventually this should change to use get_cyclecount() instead, but that
can't happen if get_cyclecount() is calling nanotime() instead of
getnanotime().
