A p5/133 machine that I have at home panic'ed while resetting ata
devices this afternoon.  The disk at /dev/ad0 sounded like it was
going off, and after a couple of attempts to reset the ata devices,
this panic happened.  The dmesg and backtrace of the kernel that
panic'ed are attached.  I suspect a hardware failure, and not a
freebsd bug here.  Does this look like a dying disk to you too?

In the mean-time me runs to backup his data on cdrom's once again,
since if the disk is dying, it can practically die any time -- even
before somebody else recognizes this as a hardware problem, and
replies.
