The r8169 driver in 2.4.22 with or without debian patches/acpi/usb devices sharing the same interrupt: the driver always ends up locking the machine by having indefinitely much to do in the interrupt handler?
Commented the printk out, still hangs the machine anyway. It happens even without a cable in the card. I have found no references to any bug reports at all with this card, and I cant see any bugfixes being in 2.5/2.6 but not 2.4 either. I can see the card TX/RX:ing a few hundred packets or more (3-60 secs) before hanging.
Any way to debug this, or should I just try 2.6?

2.6 will have the same problem. I have a version that uses NAPI that shouldn't hang.
It seems to work fine, but didn't want to submit it without more testing.

Are you sure you're not thinking about 8139too, not r8169?
