Public bug reported:

I have this problem with 2 PC's running Dapper Drake Beta (Last Upgrade today).
The USB-Device gets connected and is also mounted automatically. But syslog already writes down some errors:

Then i write some files on the Device. Sometimes the copy job "hangs"
for a few seconds.

Then i want to eject the device but it doesn umount (manually umount
also doesnt work). When i remove the cable from the PC i get this in my
syslog:

[4295245.713000] sd 1:0:0:0: rejecting I/O to device being removed

The files that i have transferred to the device are corrupted (0 bytes).
I can write to it with Windows XP / Vista without any problems, tried
with Knoppix and had the same. The USB-Device is brand new (arrived
today).
