Hi...
I just tried your patch (after patching all the way up
to 2.4.5-pre4) and I can say that it didn't make any
effect in my setup.
I did test my particular card in another motherboard,
and it was working with 2.4.3, so I know that the card
itself isn't faulty.
I'm not really familiar with the OHCI driver code, so
I'm not sure where to start in debugging the problem.
Are there traces that I should add in order to help
nail down the problem?
By the way, just fyi, I'm not so confident about this
motherboard. My dad gave it to me -- he works for IBM,
and worked with Cyrix on the development of their
6x86. It's most likely a semi-development board.
Still, all the same, it's the fastest I've got :)
Thanks,
-Karl
