hello,
Same kinds of problem here. It depends on the removed module. I mean: "rmmod loop" or "rmmod pcspkr" works. But "rmmod snd_ens1371" or "rmmod ohci1394" hangs.
Sysrq-T when rmmoding snd_ens1371 :

It looks like we're getting stuck in the wait_for_completion() in the new klist_remove().
D'oh! It's getting hung while waiting to remove the current node from the list (which it can't remove because it's being used). The patch below should fix it.

Ok, I can confirm this patch solved the problem.
