Hi,
the hostap driver produces an oops at boot time for me. I use a prism2 compact flash card.
Its seems that this is because the driver receives irqs before it is ready to do so.
I found a patch that solve the problem, but it looks more like a hack.
Any suggestions how to solve this in a better way?
Regards,
Thomas
