I built a kernel from CVS yesterday, installed it and rebooted this
morning.  It panicked with the message (manually copied):

  ...
  mounting root from ufs:/dev/amrd0s1a
  panic: Don't call insmntque(foo, NULL)
  Debugger("panic")
  Stopped at Debugger+0x45: xchgl %ebx, in_Debugger.0

This message appears in /usr/src/sys/kern/vfs_subr.c

Any suggestions?

Thanks.
