Re: tlbia and PPC603

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

Your xmon trace show something interesting: xmon itself crashes with a
trap 300 while trying to access the hash table. The hash beeing mapped
with a BAT, that shouldn't be an issue with the TLB handlers nor with
a stale TLB entry. I currently fail to see what could be going on there,
could you try to reproduce that crash ? In this case, once "h" fails
within xmon, type

 di %pc
 r

and send me what it days.

Ben.
