This is fixed in current binutils.  Current binutils also fixes non  
equivalent aliasing
bug that affects PA8800/PA8900 systems.

IAOQ head provides the location of interruption.  It was a instruction  
memory
protection fault.  Since this is a kernel address, this likely  
indicates the page
tables weren't setup correctly, or the instruction cache wasn't  
flushed correctly.

I'm thinking it would help to localize the change that introduced the
interruption.
