Re: incorrect super block w recent changes

[Martin Husemann <martin%duskware.de@localhost>]

I have another instance of this problem and made the code dump a few more
values:

wd0 at atabus0 drive 0
wd0: <SAMSUNG HM120IC>
wd0: 111 GB, 232581 cyl, 16 head, 63 sec, 512 bytes/sect x 234441648 sectors
boot device: wd0
root on wd0a dumps on wd0b
cylinder group size mismatch: fs_cgsize = 0x4800, fs->fs_cgsize = 0x4000, CGSIZE(fs) = 0x4001
sizeof(struct cg): 0xb0
howmany((ipg), NBBY): 0xb60
howmany((fpg), NBBY): 0x2e14
howmany(ffs_fragstoblks(fs, (fpg)), NBBY)): 0x5c3
ffs_fragstoblks(fs, (fpg)): 0x2e14 [fpg = 0x170a0]


I guess the CGSIZE value is off by one somehow.

dumpfs shows:
