Description Alex Austin 2004-09-14 21:53:18 UTC
The kernel printed out the following when I tried to unmount my USB keychain.
I have *not* been able to reproduce this bug consistantly. I hope that the
following is useful. By the way, this happened after the keychain had been
mounted, but not used for about half an hour. If you're interested, it is a
Memorex 512 MB keychain using FAT32. I
mounted /dev/sda (not sda1 like my other fried one) for it to work.

Comment 1 Diego Calleja 2006-01-05 08:43:18 UTC
Does this still happens in 2.6.15?
Comment 2 Diego Calleja 2006-02-15 05:39:42 UTC
Set this as "NEED MORE INFO" - the reporter doesn't seems to be ping-able. If
someone can reproduce this in latests versions please reopen
Comment 3 Adrian Bunk 2006-04-22 13:04:33 UTC
Please reopen this bug if it's still present in kernel 2.6.16.
