Errors with USB Disk

[Markus Schaber]

Hi,

I'm trying to use an USB Disk (IDE Disk in external USB Case), but
strange file system errors occurend and tools as dosfsck reproducably
hang.

kingfisher:/home/schabi# uname -a
Linux kingfisher 2.6.0 #1 Wed Dec 24 19:16:00 CET 2003 i686 GNU/Linux
 
kingfisher:/home/schabi# cat /proc/version
Linux version 2.6.0 (root@kingfisher) (gcc-Version 3.3.2 (Debian)) #1
Wed Dec 24 19:16:00 CET 2003

I attached a kernel log excerpt, it seems as there's a bug in the slab
allocater.

As I used 2.6.0, was there some work up to now (2.6.2rc2) in this area
so I should test using this newer kernel again?

I'm willing to do some debug work and run tests if you tell me what to
do, but I have very limited kernel developer knowledge.

Thanks,
Markus
