I was just trying out 2.4.15-pre4 and noticed that I am
completely unable to create partitions on my magneto optical
drives (2048 byte hardware sectors). Using fdisk to (try to)
create a single partition uttery fails. dmesg shows:
ll_rw_block: device 08:10: only 2048-char blocks implemented (1024)
sd.c:Bad block number requested I/O error: dev 08:10, sector 0
SCSI device sdb: 310352 2048-byte hdwr sectors (636 MB)
sdb: Write Protect is off
sdb: unknown partition table
SCSI device sdb: 310352 2048-byte hdwr sectors (636 MB)
sdb: Write Protect is off
sdb: unknown partition table
With 2.4.13-ac5 doing the exact same thing works fine with the
following showing up when running dmesg:
ll_rw_block: device 08:10: only 2048-char blocks implemented (1024)
SCSI device sdb: 310352 2048-byte hdwr sectors (636 MB)
sdb: Write Protect is off
sdb: sdb1
SCSI device sdb: 310352 2048-byte hdwr sectors (636 MB)
sdb: Write Protect is off
sdb: sdb1

Looks like either Andrea's block device in page cache or the updated
partition code broke stuff.
