Hi,
I realized that I've had this patch in my tree for a while, and forgot
to send it to you and lkml. The patch below fixes bug number 923:
http://bugme.osdl.org/show_bug.cgi?id=923
(basically keeps us from calling pci_find_device from interrupt
context.)
It's been tested by a few people with this device, and they say it works
just fine for them. Please forward it on up the food chain.
thanks,
greg k-h
