OOPS when copying data from local to an external drive (ieee1394)

[Dmitry Torokhov <dtor_core@ameritech.net>]

Hi,

I started getting oopses when cpying data from local IDE to an external
Firewire drive. Not always, but quite often. The kernel is a bk pull a
day before 2.6.4-rc2 was released, I do not see any ieee1394 updates
since.

Unfortunately the oops was not saves in the logs, so here is what I managed
to write down:

Oops: 00002 [#1]

Code: ...

This OOPS is with NVIDIA module loaded but I have seen exactly the
same trace without the module loaded.
