Hi,

I'm just upgraded to kernel 2.6.24 and I'm seeing a kernel OOPS every time I unload the snd_ymfpci module...

Below is what I see in my log. My naive interpretation of this is that the system is barfing in the interrupt handler at the time it is trying to free the interrupt.... so maybe the interrupt hasn't been disabled properly before the free_irq() call? As I say, it's a naive interpretation.

Anyway, I'd appreciate it if somebody could look this over and tell me what my next step should be. I'm available to debug if necessary.

Thanks,

Gerard
