Red Hat Bugzilla – Bug 131204
usbdrive producing ub I/O errors when plugged in
Last modified: 2007-11-30 17:10:48 EST
Description of problem:
2.6.8-1.533smp and kernel-2.6.8-1.532smp
produce ub I/O errors when my ioplus pocketdisk usbdrive is plugged
in. The read/write indicator light on the drive flashes repeatedly as
well until i unplug the device.
kernel-2.6.8-1.526smp and previous kernels seem to handle this device
well, and produce sda1 device that is mountable.
Attached you will find a portion of /var/log/messages created on
/proc/partitions lists with the device inserted:
125 0 25 uba
and of course mount /dev/uba /mnt/test doesn't work
/dev/uba: Invalid argument
mount: /dev/uba: can't read superblock
Every time I plug the device in, and even if the device is plugged in
Please direct me as to any further information I can give you.

/var/log/messages output on usbdisk insertion
It's too early to ship kernels with ub enabled (CONFIG_BLK_DEV_UB).
We should continue to use the old storage driver for now.
I think I found a fix, I'll have it recirculate through the upstream.

Candidate #1 - fail opens on empty devices
should this bug report be closed?
I originally reported it against a fedora development kernel but since
fedora development kernels no longer attempt to use the ub module,
should report be closed out?
Or are you using it to track ub specific issues not associated with
available binary kernels?
Jef, you are the reporter. Developers are not supposed to close bugs,
unless the reporter fails his duty.
This bug did its work. I have fixed the problem you identified.
As for the bug, eventually, I'd poke you with a NEEDINFO...
