recent bge(4) changes causing problems

It seems recent changes to the bge driver are causing
some problems with my hardware where the watchdog is
now timing out.

/var/log/messages contains

The last 2 bge messages are from me manually using 
ifconfig to bring my net connect back to life.

In the time that it's taken me to compose this message
the timeout has fire again.
