Ok; now I have a similar failure case for you (using your updated
code): Compaq LTE Elite laptop. Working wd0 probe strings:
wdc0: unit 0 (wd0): <IBM-H2344-A4>, multi-block-4, sleep-hack
wd0: 328MB (672525 sectors), 915 cyls, 15 heads, 49 S/T, 512 B/S
ad0 probe output:
ad0: <IBM-H2344-A4/G4I_A8C0> ATA-? disk at ata0 as master
ad0: 549280MB (1124925450 sectors), 915 cyls, 15 heads, 49 S/T, 512 B/S
ad0: 16 secs/int, 0 depth queue
...
Considering FFS root fs.
changing root device to ad0s1a
ad0: invalid primary partition table: no magic
changing root device to ad0a
ad0: invalid primary partition table: no magic
error 22: panic: cannot mount root (2)
What I find fascinating is the LBAsize for the total # of sectors
reported by the new driver code. 1124925450 is 0x430D000A. The
correct amount, 672525, is 0x000A430D. Sounds like a word-swapping
problem somewhere. Maybe LBAsize should only be used if necessary?
