Several of us on the list had the same/similar problems.  AFAIK the only
fix at this point is to run w/ no more than K6 optimizations.

Check the archives for
-> Only 10 MB/sec with via 82c686b (towards the end of the thread)
-> thunderbird 1.2G + kk266 + 2.4.x oops

It seems to be something wierd with the way memory is handled on the iwill
board.
