I have attached the dump file. Mind you although I have checked the file
carefully I had to type it all in, thus there could be one (or two) typo's.

Up to a certain revision of the StrongArm (I think k) there was a bug
regarding the STM opcode. In short: if you stored multiple registers with
STM and you happened to go over a page boundery wich was not in memory, this
would give page error. netbsd would then load the page from the swap into
memory and the write could continue. However the STM opcode would not
continue with the not saved registers but would start all over again, but did
this to the wrong address.
This might not be discribed exactly but I hope you get the picture.
Thanks for your help
