Hello Ralph,

It's been a long time since heard your voice. I thought you had been damn busy.
Nice to hear from you.

I think you should call pci_enable_device() before request_irq, etc.


Sure i will try that out..

AFAIK, the pci_enable_device() can change resources like IRQ.
That's probably what causes these errors. Just print out the irq number before and after pci_enable_device() to check if that's the problem.




I will check this out. I will come back on this soon.

Manu
