Hi,
I just tried booting 2.4.19-pre9-ac3 (SMP, 1.25 GB, devfs) with the "nosmp single" flags to try and debug a Firewire problem, and I found this oddity in /proc/interrupts:
CPU0 0: 28797 XT-PIC timer 1: 629 XT-PIC keyboard 2: 0 XT-PIC cascade 8: 0 XT-PIC rtc 9: 0 XT-PIC acpi 14: 10299 XT-PIC ide0 15: 26 XT-PIC ide1 16: 0 none usb-ohci 17: 0 none ehci-hcd 18: 0 none ohci1394 19: 0 none usb-ohci, usb-uhci NMI: 0 LOC: 0 ERR: 0 MIS: 0
Last time I booted an SMP kernel with "nosmp", there were no IRQs > 15 and all the PCI devices were remapped to 5,7,9,10,11 etc.
This doesn't look good...
