FWIW, thunderbird-3.1.1 runs fine on exactly the same kernel.

Could this be a side effect from DEADLKRES or as a result of
a exclusive mutex lock (lock order reversal) ? I'd add option
DEBUG_LOCKS and/or
WITNESS_SKIPSPIN, to disable witness checks on spin mutexes, as
explained in the NOTES file.

cheers,

It should just be the GENERIC kernel, it is attached for completeness.

Please show us the kernel config too. It compiles and runs
without side effects on FreeBSD 8.1 (GENERIC) and native gcc...

cheers!

Fair enough...

a trace of about the first 10 seconds generated by 'ktrace -di
thunderbird'
is available at ftp://rene-ladan.nl/pub/freebsd/ktrace.out

You'll need a amd64 machine to kdump it.

Note that nothing user-visible happens when I start thunderbird.

a kernel backtrace would be a nice visual aid to debug!!!

Cheers,

Hi,

it looks like on this CURRENT:
FreeBSD acer 9.0-CURRENT FreeBSD 9.0-CURRENT #0 r210736: Sun Aug 1
21:51:37 CEST 2010
r...@acer:/usr/obj/usr/home/rene/freebsd/clangbsd/sys/GENERIC amd64

thunderbird is always stuck in ucond upon start, however it is
killable.

This is a clangbsd kernel (GENERIC, with WITNESS), r210319 with
gccbsd
userland, r209980 and gcc-compiled up-to-date ports.
The following modules are loaded:
