given the folowing kernel config && dmesg i have this in my 
/var/log/messages every now and then with a distance of 30 mins, 1 hour 
between repeating:

bge1: watchdog timeout -- resetting
bge1: block failed to stop: reg 0x3400, bit 0x00000002

also conectivity breaks to my isp plugged in the bge(4)s and THIS HURTS!


the setup is as follows:
              
isp1--------|bge0-(bridge0)-bge1|---->
isp2--------|ex0--(bridge1)--ex1|---->
isp3--------|wm0--(bridge2)--wm1|---->
                (this machine)         (router, lan)
