Kernel panic on most recent snapshot

[Matthew Dillon]

::
::Anyone else getting a kernel panic using the most recent HEAD revision?
::
::When booting from CD:
::
::	Mounting root from cd9660:cd0c
::
::
::	Fatal trap 12: page fault while in kernel mode
::	fault virtual address = 0x8
::	...
::	...
::	...
::	kernel: type 12 trap, code=0
::	Stopped at	dsioctl+0x64	cmpl 0x8(%eax),%edx
::
::
::When booting from HD:
::
::	Mounting root from ufs:/dev/ad0s1a
::	no disk named 'ad0s1a'
::	setrootbyname failed
::	ffs_mountroot: can't find rootvp
::	Root mount failed: 6
::
::	Manual root filesystem specification.

    I am having problems reproducing the actual assembly being reported
    as the failure point.

    Are you using any special options when compiling or overriding the
    compiler? (using GCC-3 instead of GCC-4)?

    I am doing a full world rebuild, install, and then rebuilding the
    kernel with the new world right now to see if that produces different
    code.
