Hello, I got this problem for the first time today, while I was doing anything unusual, (even the traffic on eth1 was low), eth1 stopped working, in the log I see : May 11 11:37:16 [kernel] irq 16: nobody cared ! I tried ifconfig eth1 down; modprobe -r b44; modprobe b44; ifconfig eth0 up, but the iface was not working until reboot. Unfortunately I've lost the dmesg lines, but it contained traceback with last line in b44_interrupt. To my non-kernel-hacker, eye, b44c:883: return IRQ_RETVAL(handled); seems supsicious. The card is integrated in my HP Compaq notebook, i915/910GML chipset.
