Hi folks,

In a i386 virtual machine, 512MB RAM, after few hours running test/stress/tuxload, the system panics.
I haven't tried it in x86_64.

Unread portion of the kernel message buffer:
panic: assertion "ref >= &td->td_toks_base && ref->tr_tok == tok" failed in lwkt_reltoken at /home/source/dfbsd/sys/kern/lwkt_token.c:778

Cores are available in case someone wants to take a look.
