Hi!
I don't have a PPC but I think that you should give some other info
with your backtrace:
_ When does it occur? Boot time or special cases?
_ Can you reproduce it? How?
_ Does this bug still occur on the last stable kernel?
Regards :-)
My kernel is from Montavista, so i don't know if possible to compare
to the current one.
I can't reproduce it.
Hope that someone can give me a little translation of backtrace, so
i can go to check.
My system doesn't have swap. Can i disable swapper?
