Problem mounting Motorola USB device

Problem mounting Motorola USB device

[Alan]

Initializing USB Mass Storage driver...
scsi6 : SCSI emulation for USB Mass Storage devices
I have a Motorola phone that mounts as USB storage.  The phone used to
mount under 2.6.24 on Fedora 8.  Under the latest kernels, however, it
does not want to mount.  The device gives an odd media error at towards
the end of the device.  It gave that before, but would still mount.

Does anyone have an idea what is going wrong?

How can I mount the device anyway?  (The /dev/sdb does not get created by
usb-storage in this case.)  I know I probably need a new memory card.  I
would like to recover this one first.

Here are the /var/log/messages...

Forgot the kernel version.

Fedora 9 2.6.25.10-86.fc9_x86_64

I am wondering if this is a kernel problem or a udev problem.  Should I
diff the udev rules between f8 and f9?

It appears to be a maze of twisty configs, all alike.

It's a 2.6.24 -> 2.6.25 regression.

Weird. Actually, I would rather blame the partitioning code than
the usb-storage as such.

Want a practical suggestion? Try to stick the card into a common
many-in-one reader, a SanDisk SDDR-somenumber would usually work.
Save the data.

Well, duh.

BTW Andrew added:

Maybe in FAT... See the sector number (1987576).

BTW, all Fedora kernels have usbmon enabled. May I see the trace?
Best of all, take the one from the working 2.6.24 (if such install
is still available). It would become obvious if usb-storage began to
do something different.

Obligatory notice: I don't think ub would fix this.

This actually causes a kernel oops.  I will post debug info soon.

I will get more info now that OSCON is over.

Probably unrelated, but must be fixed.

Thanks.

One question: can you switch to self-built kernels instead of supplied
by Fedora, just for this bug? It would be easier for me to look at
(I'm speaking in the USB hacker capacity here rather than as one
of Chuck's underlings).

Which tree do you want me to build from?

I think 2.6.26 would be a good place to start. Also I think the best would
be to populate the .config from /boot/config* that Fedora supplies. It takes
longer to build, but makes it more likely that we reproduce one or both
of the failures you saw (phone not mounted and the oops). You will need
to run  mkinitrd /boot/initrd-2.6.26-alan.img 2.6.26-alan or something
like it, Fedora's userland and .config pretty much require it.
