In this case, are we sure that the 601 problems are introduced by this
change ? Historically, there have been other 601 related problems, like
code touching HID0 without checking processor version or so.

Another possibility is an ordering problem, it seems that the code
reloads all the BATs from the BAT array setup by mm/init.c. Is it possible
that the crash happens this late and do you still need BAT3 after this ?

Maybe the fix will be as simple as writing 0 to the IBATL in LOAD_BAT so
that we are sure that the BAT is disabled before being reloaded, or call
again clear_bats before the series of LOAD_BATs.
Well, Andreas re-did the tests with my latest fix (which was to remove
the bogus PAGE_GUARDED in the 601 case) and with the mftb 601 fixes and
his kernel now works.

Ben.
