>Description:
bge0 at pci2 dev 0 function 0: Broadcom BCM5751 Gigabit Ethernet
bge0: interrupting at ioapic0 pin 16 (irq 11)
bge0: pcie mode=0x105000
bge0: ASIC BCM5750 A1 (0x4001), Ethernet address 00:11:43:xx:xx:xx

until I pxeboot, every time I try to send a packet I get an endless stream of:

bge0: watchdog timeout -- resetting
bge0: block failed to stop: reg 0x1400, bit 0x00000002
bge0: pcie mode=0x105000
bge0: watchdog timeout -- resetting

>How-To-Repeat:
reboot from windows into NetBSD and try to use the NIC
>Fix:
Something is likely wrong with interrupt establishment or PCI Express code as there is no entry for ioapic pin 16 (irq 11) in vmstat -i when it isn't working, yet there are almost 500 softnet interrupts.

The chip passes Broadcom's NIC diagnostics, and has worked flawlessly in windows for over a year. Memtest86+ tested system memory for days with no errors.
