Intermittent problems on PowerPC

I'm using Andrey's latest eepro100.c on a PowerPC-based CompactPCI board.
The odd thing is that I've had the thing working and even had a
dual 82559 PMC module inserted and had all three interfaces working
after nfsrooting and configuring the other ones.  Basically, I'll
go through some boots where the thing just won't receive anything.
With kernel level autoconfiguration on as below, I can see it transmit
BOOTP request and my server responds, but apparent it never receives
the response because it doesn't continue.

Has anybody had success with the latest eepro100 on PowerPC?  I've
included a dump with debugging on below is anybody has any ideas.

Thanks,
Matt
