I'm sure this is no suprise to you, but I can update my sources to the commit *just before* you made the PCI interrupt switchover and everything works fine. What can I do to help you debug this further? Nate ps. Hot swapping the ethernet card now rarely works, although it now seems to be not working very well with a kernel compiled with the older code, so I'm not sure what's up. I suspect that it's an issue with using IRQ 11, which is serviced *after* IRQ 9 (the interrupt used for the ethernet card). I'm guessing the removal is causing a spurious interrupt for the card that is serviced before the removal event, causing the hang. With the older FreeBSD kernels, I allocated IRQ 3 to the PCIC for insertion/removal events, and this IRQ is serviced before IRQ 11. However, when I allocate IRQ 3 to the PCIC (using machdep.pcic.irq), it panics whenever I insert/remove a card. :( To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
