Summary: USB storage doesn't work on my Sony Vaio C1VE
Kernel Version: 2.5.66-bk2
Status: NEW
Severity: blocking
Owner: greg@kroah.com
Submitter: stelian@popies.net
Distribution: RedHat 8.0
Hardware Environment: Sony Vaio C1VE (same as C1VM/C1VN in other countries),
external USB floppy drive, internal memory stick USB reader
Software Environment: mount...
Problem Description: Neither the floppy drive nor the memory stick reader
work, even if they seem to trigger different bugs
First of all, both the floppy drive and the memory stick reader work
perfectly under a 2.4 kernel.
When used with 2.5.66, the memory stick reader is seen as a USB device, but
not always detected as a SCSI disk. The floppy drive is immediately
recognized as a USB device and a SCSI disk.
However, trying to read/write data (with dd, mount etc) doesn't work,
errors are shown in the kernel logs and the operations are _very_ slow
(the mount process hangs for 5 minutes before giving up, it's wchan being
scsi_wait_req).
I'm attaching several kernel logs:
* memstick.ok, floppy.ok: kernel logs of successful operations on a
2.4.21-pre6 kernel
* memstick.bad, floppy.bad: kernel logs of failure on 2.5.66-bk2
* usbstorage.oops: an oops I got while playing with 2.5.66-bk2 and tried to
remove usb-storage to see if it helps to reinsert it. I'm attaching it
here, and not in a separate bug report because it may be related to my
failures.
I can give more information if it is needed (enable debugging in USB and/or
SCSI somewhere, test patches etc.), just say it.
Stelian.
