| |
HI,
I noticed that on the abit kt7A MBs that i have, with via KT133A chipset, after i installed the kernel 2.4.9-ac10 (ac11 and 12 as well), at boot i get this message,
Sep 21 11:52:11 DarkStar kernel: ice 00:0b.0 Sep 21 11:52:11 DarkStar kernel: spurious 8259A interrupt: IRQ7. immediatelly before scsi adaptec detection and inizzializzation.
doing a cat /proc/interrupt I can read
ERR: 1
As many people I have parport on irq 7, and the parport simply works anyway (tested with a printer).
I was thinking to an HW problem, but with vanilla 2.4.9 kernel I do not get this message, and the code in arch/i386/kernel/i8259.c that should detect this spurious interrup is just the same on those two kernels. Changes are related to X86_IO_APIC, and I think this is the reason why this spurious interrupt is detected, but I would like to know if i should think I have some HW problem going on that stardard kernels do not detect.
bests Luigi
