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

On my System, changing max_sectors to 128 doesn't help reliably. I'm
currently testing if 64/32/16/8 will work better.
Bye

Thanks a log, we'll try this on our machines.
Yours,
Markus

Michael, Markus, Et. Al.
We are seeing the same problem ( USB hangs ) on 2.4.24 and 2.4.25-pre7 w/ the
patches submitted by Oliver and Alan S. We're copying about 15GiB of data
between an IDE and USB drive, and see the hang occur somewhere in the first
1GiB of data transferred.
Changing max_sectors to 128/64/32/16/8 in the scsiglue.c doesn't make any
difference as far as stability goes. Unfortunately, once the system locks up,
it ceases responding even to the SysCtl hack.
I'm in the process of performing tests on various platforms and verbose
logging usb_storage via serial console. As soon as I have some results I will
be posting them to the linux-usb-devel list.

Please try 2.6.1 at the least, and if you can 2.6.2-rc2. There's been a
lot of cleanups and minor fixes in the USB and scsi area in those
kernels.
thanks,
