Subject: Copying file with bad utf byte sequence in filename to rw UDF filesystem
 panics

Binary package hint: linux-image-2.6.24-22-generic

I have a file on ext3 that has a spurious 0x8A char in it's filename.
When I try to copy it to a R/W UDF volume I get a kernel panic.

$ ls Air\ -\ Le\ Soleil\ Est\ Prï¿½s\ De\ Moi.mp3 | hexdump -C
00000000  41 69 72 20 2d 20 4c 65  20 53 6f 6c 65 69 6c 20  |Air - Le Soleil |
00000010  45 73 74 20 50 72 8a 73  20 44 65 20 4d 6f 69 2e  |Est Pr.s De Moi.|
00000020  6d 70 33 0a                                       |mp3.|
00000024

The filesystem has to be mounted with iocharset=utf8

Is this related to http://lkml.org/lkml/2008/1/30/483

thanks
