I started getting a panic like this immediately after bootup around the same
time as everyone else's problems (although my last build was from March 1st,
and I've only just started using INVARIANTS/WITNESS and ``makeoptions
DEBUG=-g'' which were recently aded to GENERIC). The latest commits don't
seem to have changed anything.
During boot (interleaved with IPv6 stuff), I get this:
lock order reversal
1st 0xc04a7380 mntvnode @ /usr/src/sys/ufs/ffs/ffs_vsops.c:1007
2nd 0xcd105aec vnode interlock @ /usr/src/sys/ufs/ffs/ffs_vfsops.c:106
Just around the time of the console login prompt (consistently), I panic:
[warning: likely to contain hand transcription errors]

What changes should I start to make first to narrow this down? (I'll try to
get kernel dumps going, though I haven't had much success with these in the
past.)
Cheers,
Mark.
