I'm writing a RT-driver for a PCI-Card. Sometimes my PCI-Card and the
ethernet card have the same interrupts.
In init_module I call rtl_request_irq, but after the next interrupt of
the ethernet card (so I think) the system crashes (freeze, reboot,
kernel panic). My interrupt handler is never called. The calltrace of
kernel panic looks like a lot of recusive calls.
If my PCI card has another irq, it runs well. I use RTL 3.0pre9.
Are there problems if Linux Device Driver and RT Driver share interrupts
?
