Speaking of ARC and SRM, I have an AXPpci33 whose flash won't accept
either ARC or SRM.  When I try to update the image to SRM it bombs after
precharging.  Here's what I get:

Apu-> update srm

APU-I VERIFY LOADED ROM IMAGE
0x52400
APU-I LOADED ROM IMAGE VERIFIED
APU-I VERIFY LOADED ROM IMAGE
0x52400
APU-I LOADED ROM IMAGE VERIFIED
APU-I ****** ROM CONTENTS WILL BE DESTROYED   ******
APU-I ****** READY TO PROGRAM DEVICE ? (Y/N ) ****** y
APU-I ROM SET NOT ERASED
APU-I PRECHARGING DEVICE
0x41000
Rom 3 Pgm Fail Offset 0x1610 Exp 0x0 Act 0x40
0x41611

Updateing the arc console fails in much the same manner.  Has anybody seen
something like this before?
