kernel/2964: kernel panic when trying to fdisk/disklabel volume on twe board

>Number: 2964

>Environment:
        

	System      : OpenBSD 3.1
	Architecture: OpenBSD.i386
	Machine     : i386

>Description:

        running an fdisk or a disklabel on a volume that is on
        a 3ware 6800 series board causes a kernel panic.  the 3ware
        boards i have tried this on all have the latest firmware and
        i did wait for the volumes to finish profiling.  i have repeated
        this experiment with the same results on 3 different motherboards
        and three different 8 port 6800 cards in addition to a 2 port 6800
        card.  this problem has been around for a while, and I tried to
        get some solutions via misc@openbsd.org to no avail.  i see in 
        the daily log some panics were fixed at some
        point before oct 3... my sources were updated on oct 8 and
        this problem is still there.

>How-To-Repeat:

        install openbsd on a separate root disk, say an IDE disk.  boot 
        up, try to setup the volume on the twe with fdisk or disklabel.

>Fix:

        after installing 3.1-stable, get a floppy29b image and put it
        on a disk.  boot into that floppy, goto shell and use the
        fdisk, disklabel and newfs tools to setup the volume.  reboot
        into 3.1-stable and now you can edit the fstab and mount
        the volume without any problems.
