Here's a backtrace of a crashdump that should be more helpful:

Well, I haven't had much luck tracking down the exact cause. For some

Hi,
on today's -current, I get the following panic when starting gnome from
xdm; a kernel from 2/10 works with today's world, so it must be
something in the kernel that changed over the last week:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; lapic.id =
fault virtual
FWIW, this looks nearly identical to the panic I reported last night in
the thread VFS panic (possibly NFS locking related?). I didn't manage
to catch the ddb trace and had to work postmortem with a crash dump and
gdb. But it looked just like here.

I missed your message, just read it: yes, that sounds similar.
