Thanks for testing! I have no clue what goes wrong atm. I will come back to you if I get any ideas. Could you try to build an UP kernel and check if that one is more reliable? Not that it will help with the bug you report here - but it will tell more about the current state of the UP version of the sparc32 kernel.
