| |
Something broke between 2.4.20 and 2.4.21-pre3 which is causing interrupts to not be routed the second CPU. I saw the problem on one box and copied the kernel to another which then had the same problem (both ASUS P2B-DS boards, one with PIII CPUs, one with PII CPUs).
[sroot@devel:/]# cat /proc/interrupts CPU0 CPU1 0: 114480 0 IO-APIC-edge timer 1: 2 0 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 8: 3 0 IO-APIC-edge rtc 16: 30707 0 IO-APIC-level eth0 19: 3260 0 IO-APIC-level aic7xxx NMI: 0 0 LOC: 114405 114404 ERR: 0 MIS: 0
With 2.4.20:
[sroot@devel:/root]# cat /proc/interrupts CPU0 CPU1 0: 23627 27340 IO-APIC-edge timer 1: 0 2 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 8: 2 1 IO-APIC-edge rtc 16: 1671 2 IO-APIC-level eth0 19: 965 979 IO-APIC-level aic7xxx NMI: 0 0 LOC: 50893 50891 ERR: 0 MIS: 0
...If nobody knows what happened immediately, I'll try narrowing it down to the patch.
