>Description:
My PCI Broadcom 5701 Gb ethernet card, which works nicely under the shipped 
kernel in 5.0.1 (not to mention Linux 2.6.26) is giving the following error 
under this -current kernel and refusing to pass any traffic:

bge0: watchdog timeout -- resetting
bge0: block failed to stop: reg 0x4800, bit 0x00000002

Kernel config is an unmodified "MONOLITHIC" built with build.sh and based on 
today's CVS version of the code.
>How-To-Repeat:
On my computer, boot this kernel instead of the stock one. Booting stock kernel 
resolves issue.
>Fix:
