[PowerPC] Bug in IEEE1394 implementation on PowerBooks

[PowerPC] Bug in IEEE1394 implementation on PowerBooks

[Andrew Patrikalakis]

[1.] Putting the PowerBook to sleep with ieee1394 modules loaded causes a bus error after waking up the machine and trying to use the bus
[2.] 	If ieee1934 modules are loaded (ieee1394, ohci1394 and sbp2) on 
a PowerBook and the pbook is put to sleep with the modules loaded, if you
try to use the modules after waking the machine up it causes a Bus error

Attached devices: none
[7.7.] It's fairly obvious what this problem is - the device isn't shut down
properly at a sleep request (it doesn't request to be shutdown from the PMU
code). This should be an easy fix that I can do, but I'd need some pointers
to other drivers that do this (insert a sleep notification into the PMU
driver).
[X.] If someone can e-mail me with the pertinent information, I'd be
happy to fix the problem ;-). Or anything else for that matter, I'm
not subscribed to the list ^^; I'm also relatively sure it hasn't 
been fixed in the latest version (2.4.20-pre9) as the pertinant parts
of the code aren't different.

Check the USB OHCI driver.

If you get something, carry it on over to linux1394-devel@lists.sf.net.
I'd help out but my G4 is on the rocks.
