I am not mounting /media/mmc*
I think that is some thing with signal arrives at
sleep_thread(struct fsg_dev *fsg) function ...

Which version of the Linux kernel are you using?
If you enable debugging in g_file_storage, what shows up in the dmesg
log?
When the rmmod is waiting, what does a stack trace (Alt-SysRq-T) show?
Really, you shouldn't expect people to be able to help if you don't
provide any information...

I am using the last omap git tree from
