Hello all,

after using a USB storage device (a Kingston DataTraveler 8GB flash
stick) in the sheevaplug for some hours, at one point the device
stopped working until I replugged it in.

The system kept stable, while all this happened.

Here comes the 'dmesg' part:

EXT3 FS on sda1, internal journal
EXT3-fs: mounted filesystem with writeback data mode.

It's a vanilla kernel built with gcc 4.3.4 . If you need more
information, I can compile special versions of that kernel to get some
additional information.
