Does the 8260 have BATs ?
If not, can you check if the code for ret_from_except is entirely
contained in a single page or spans over 2 pages ?
(objdump should help here).
If it is the case, then you need some of my fixes to make the exception
return path safe against TLB misses (or hash misses, dunno if you have
a hash table on this CPU).
