Hello list,
it's me again. I report a new problem with the other disk (so the previous
problem is still solved, don't worry).
The kernel I used is a 2.6.11-rc4-bk6 with the following patches : 
http://sjdcolin.free.fr/tmp/patches/

I did the tests with usb-storage debug and usb debug activated, the logs are
here : 
http://sjdcolin.free.fr/tmp/

The test itself : a fsck.ext3 (or ext2, depends) on the partition of the
offending usb2-rated disk.
logs-1 : fsck.ext2 on sda1, blocks in the middle (but not always at the same
place)
logs-2 : fsck.ext3 on sda5, blocks also while fscking
logs-3-scsi : same as logs-2, but with scsi logging fully activated (all 7),
as the problem might be related to scsi
logs-4-uhci : same as logs-2 and logs-1, but with uhci instead of ehci (the
fsck was successful).

The lists.tar.gz shows previous lsusb and lspci, it did not change much so I
did not regenerate them. The problem might be only related to scsi handling
of the firmware of the disk, but I prefer to post here to go the "right
way", from the downhill possible causes to the uphill possible causes.
I attached an excerpt of the logs where the errors first appear. After a
quick googling, I had seen similar but not exactly identical error reports.

What is "interesting" is that the copy of many big files from another (usb)
disk did not cause any error, a huge reading neither (for a md5sum of the
copied files), while a simple fsck causes problems. Maybe fsck sends
particular, disk-controller related commands, making me say that the
problem could be located at the scsi level.

Any idea ?
Regards,
Samuel Colin

PS : I'm not on the list, so please put me in Cc: so I can follow the
discussions.
