I've been unable to boot any kernel I've built since about March 11
and I've narrowed it down to the GEOM_MBR option.
With GEOM_MBR I get a kernel page fault error when trying to
mount the root filesystem at boot time.

Information from DOS bootblock is:
The data for partition 1 is:
sysid 11 (0x0b),(DOS or Windows 95 with 32 bit FAT)
start 63, size 4208967 (2055 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 261/ head 254/ sector 63
The data for partition 2 is:
sysid 15 (0x0f),(Extended DOS (LBA))
start 4209030, size 52018470 (25399 Meg), flag 0
beg: cyl 262/ head 0/ sector 1;
end: cyl 1023/ head 254/ sector 63
The data for partition 3 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 139926150, size 16370235 (7993 Meg), flag 0
beg: cyl 1023/ head 0/ sector 1;
end: cyl 1023/ head 254/ sector 63
The data for partition 4 is:
<UNUSED>
# /dev/ad0s3c:
type: ESDI
sectors/cylinder: 16065
cylinders: 9729
sectors/unit: 156301488
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 15321596 1048576 4.2BSD 0 0 0 # (Cyl. 65*- 1018*)
b: 1048576 0 swap # (Cyl. 0 - 65*)
c: 16370235 0 unused 0 0 # (Cyl. 0 - 1018)
Warning, partition c doesn't cover the whole unit!
Note that I put the swap partition first. Could that cause this problem?
