rmmod ohci1394 hangs in klist_remove

[Stelian Pop]

Removing the ohci1394 module no longer works, sysrq+t shows:

rmmod         D 0FF7F724     0  6044   6038                     (NOTLB)

This is with the latest Linus' git tree, on a Powerbook laptop (ppc).
Removing the module works with stock 2.4.12.

Thanks.

I've filed a bug at kernel bugzilla, so your report won't be lost.
See http://bugme.osdl.org/show_bug.cgi?id=4802

You can register at http://bugme.osdl.org/createaccount.cgi and add yourself

P.S.: Correct version number if my guess about it was wrong.
