----Security_Multipart(Mon_Oct_15_03_41_21_2007_018)-- Content-Type: Text/Plain; charset=us-ascii Content-Transfer-Encoding: 7bit I got the following panic with the Oct 14 8-CURRENT kernel. A 2-way (Opteron) box running GENERIC FreeBSD/i386 kernel with serial console access, and typing some keys just after "Trying to mount..." line appears seems to prevent this panic. Without typing any keys the box remain stopped after displaying the line, and then typing a key will cause this panic. Whether the panic occurs depends on the time between displaying the line and typing a key. ----(from here) WARNING: WITNESS option enabled, expect reduced performance.
