Thanks, it's good to know that there has been some other testing.

Does anyone have a working 32-bit kernel using the tmpalias support?  It 
would be nice
to know if the problem is a 32-bit or PA 1.1 issue.

I asked where the crash occurred because PA 2.0 mnemonics are used in 
the tmpalias
code.  On the other hand, if the failure occurs on the first flush 
instruction, the issue is likely
in the TLB insert code in entry.S.
