I was feeling pretty stupid already because nobody else seemed to have had problems :-) It definitely appears that something is wrong with interrupt assignment. drivers get IRQ 0 and can't do anything with it ... I have finally got a printout of some boot messages with a serial console. There are very few differences between a 2.4.5 and 2.4.7 boot, but those that appear relevant are related to failure in interrupt allocation (note that the serial driver also says "irq=0"). >>>> 2.4.5: ===== ttyS00 at 0x03f8 (irq = 44) is a 16550A ttyS01 at 0x02f8 (irq = 45) is a 16550A ... keyboard: Timeout - AT keyboard not present?
