About the corruption problems, I noticed:
kernel: attempt to access beyond end of device
kernel: sdg2: rw=0, want=27039680368, limit=15746760
kernel: attempt to access beyond end of device
kernel: sdg2: rw=0, want=7948148456, limit=15746760
kernel: attempt to access beyond end of device
kernel: sdg2: rw=0, want=7948148456, limit=15746760
kernel: attempt to access beyond end of device
kernel: sdg2: rw=0, want=10942330464, limit=15746760
kernel: attempt to access beyond end of device
kernel: sdg2: rw=0, want=10942330464, limit=15746760
etc...

The limit would look correct: 15746760*512=8062341120=8GB
The usb-storage seems to have a little problem with the keys geometry...
I am not even entirely filling the key; I fill it up to 60%
It happens with 2 different (but same model) keys.

# fdisk -l /dev/sdg

Disk /dev/sdg: 8086 MB, 8086618112 bytes
249 heads, 62 sectors/track, 1023 cylinders
Units = cylinders of 15438 * 512 = 7904256 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdg1   *           1           3       23126    6  FAT16
/dev/sdg2               4        1023     7873380   83  Linux

Do USB keys need special geometries (not a boot problem)?
Or could it be the corruption problem that was reported on the list with the new kernel...?

Thx,
JD
