Joanne,

Martin's boot log (including your patch) says:

Jun 19 21:19:09 merkaba kernel: [ 7891.843284]  sdb: RDSK (512) sdb1
(LNX^@)(res 2 spb 1) sdb2 (JXF^D)(res 2 spb 1) sdb3 (DOS^C)(res 2 spb
4)
Jun 19 21:19:09 merkaba kernel: [ 7891.844055] sd 7:0:0:0: [sdb]
Attached SCSI disk

so it's indeed a case of self inflicted damage (RDSK (512) means 512
byte blocks) and can be worked around by using a different block size.

Your memory serves right indeed - blocksize is in 512 bytes units.
I'll still submit a patch to Jens anyway as this may bite others yet.

Cheers,

  Michael
