Hi, 

I am currently using this patch on my powerbook to fix the problems
that USB was causing with sleep and wakeup.  Basically one of the USB
controllers was getting a spurious wakeup immediately when put it
into the suspend state.  This would cause the resume routine to be run
after we had turned off the device, causing a machine check.

Also we had some races where we would turn off the clock to the apple
OHCI cell(s) and then try to access them.  With this patch, sleep and
wakeup are quite reliable.  The patch is against 2.6.11.

Would it be the "proper" patch I was looking for in the thread named
"[PATCH] Re-power USB ports on wakeup" ?

Or does it fix different issues ? Mine fixed, with a hack I think, the
fact that USB ports kept being powered down after one wakeup out of
two. I never got any machine check, however.

Thanks,
