This happens reliably, every time. Is this a clue ?. Booting without -p boots reliably, which led me to suspect that my earlier tests may have been misleading. Sure enough - reverting to the SMP kernel without the Pasi spin_lock_bh patch does the same so it seems we probably do not need this. More test results :- Run top from serial console - OK telnet in and tar -tf a kernel tarball - this sometimes completes but always screws the keyboard input of the serial console. If it does not complete it hangs, Load average goes to 1.0. Another telnet - can kill the top session but serial kbd input is still broken - kill the serial console root shell and all is well again. Cannot kill the hung tar process. Could this mean that interrupts might be getting misrouted to the wrong CPU or process ?.
