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...
