Hi. Here is copied by hand backtrace from panic on boot: panic: Assertion ts != NULL failed at /usr/src/sys/kern/kern_mutex.c:646 db> tr panic() _mtx_unlock_sleep()+0x58 _mtx_unlock_flags()+0x94 slab_zalloc()+0x2b uma_zone_slab()+0x2b uma_zalloc_bucket()+0x124 uma_zalloc_arg()+0x25f malloc()+0xb2 eventhandler_register()+0x16c vnlru_proc()+0x43 fork_exit() fork_trampoline() Dmesg and kernel config below. BTW. I'm able to reproduce it with 4BSD scheduler as well. ===> Dmesg: Copyright (c) 1992-2004 The FreeBSD Project.
