Hi! I have crashes in MUSB code when working with USB gadget drivers.
Kernel version: linux-omap master d8ebff302ff819587377b123e900e501e4135d86
To reproduce: (USB device cable should be attached).

dd if=/dev/zero of=/tmp/disk bs=1k count=1024
mkdosfs -F 32 /tmp/disk
insmod g_mass_storage file=/tmp/disk stall=0

Wait till disk is mounted on host, then

rmmod g_mass_storage
insmod g_mass_storage file=/tmp/disk stall=0

And here we get Oops in include/linux/list.h line 93,

I guess it's the list corruption bug, right ?

I've seen that, but couldn't get it to reproduce. Now that you said, I'll try to find a fix for it.
