It does seem related to ataraid.  I just ran gdb on the kernel.debug on the 
6.0 install CD and that instruction pointer comes out to:

(gdb) l *0xffffffff8022b99a
0xffffffff8022b99a is in ata_raid_promise_read_meta 
(/usr/src/sys/dev/ata/ata-raid.c:2497).

Which corresponds to the line:


    if (ata_raid_rw(parent, PR_LBA(parent),
		    meta, sizeof(struct promise_raid_conf), ATA_R_READ)) {

It looks like it probably died in the PR_LBA macro.  Perhaps the ata-raid code 
isn't checking for a 'heads' value of 0 and it needs to?
