Question: there is really nothing which prevents bad SCSI commands
to be sent out ? I was thinking that as READ_CAPACITY is used to
initialize the /dev/sda size, sub-partitions of /dev/sda might never
be bigger than the whole.
Shouldn't it be a test in the ll_rw_blk() or otherwise that
would cause the *kernel* to error, and not a SCSI command with
illegal blocks to be send out ?
Something the user could try is to see if the problem also appears
with mke2fs /dev/sda (ie no partition). If it does, fdisk can't
be blamed.
