Mike,
I see the problem with 2.6.31-rc3. Given the content of patch ea9df4...it might
be of interest that my dasd devices have a hard sector size of 4k:
$ sudo blockdev --getss /dev/dasdf1
4096
$ sudo blockdev --getbsz /dev/dasdf1
4096
Since I always get confused by the internal 512 bytes vs. hard sector size vs.
block size vs. file system block size I dont know if that is important.
Christian
