Dear Jens Axboe,

I  do "fsck -fy /dev/sda1" on driver MAX_XFER_SECTORS 512.
The file system was not clean.
I attach mesg.txt for you refer to.

=====================================
== boot with driver MAX_XFER_SECTORS 4096
=====================================
#mkfs.ext2 /dev/sda1
#reboot
=====================================
== boot with driver MAX_XFER_SECTORS 512
=====================================
#fsck -fy /dev/sda1
/dev/sda1:clean,.............
#reboot
=====================================
== boot with driver MAX_XFER_SECTORS 4096
=====================================
#mount /dev/sda1 /mnt/sda1
#cp /root/aa /mnt/sda1
#reboot
=====================================
== boot with driver MAX_XFER_SECTORS 512
=====================================
#fsck -fy /dev/sda1
/dev/sda1: no clean,........and dump message such as the attach file 
mesg.txt.

Best Regards
Erich Chen
