I can't for the life of me figure out how one of my suspend2 users could get this on a 2.6.9 kernel: > Software Suspend 2.1.4: Initiating a software suspend cycle. > ACPI: PCI Interrupt Link [ALKA] BIOS reported IRQ 0, using IRQ 20 > ACPI: PCI Interrupt Link [ALKB] BIOS reported IRQ 0, using IRQ 21 > ACPI: PCI Interrupt Link [ALKC] BIOS reported IRQ 0, using IRQ 22 > ACPI: PCI Interrupt Link [ALKD] BIOS reported IRQ 0, using IRQ 23 > APIC error on CPU0: 00(00) > ACPI: PCI interrupt 0000:00:0f.0[A] -> GSI 20 (level, low) -> IRQ 177 > ACPI: PCI interrupt 0000:00:11.5[C] -> GSI 22 (level, low) -> IRQ 193 > Please include the following information in bug reports: > - SUSPEND core : 2.1.4 > [...] > > All work fine. > Processor and motherboard Athlon Barton 2500+@3200+, EPoX 8KRAI (KT600). > > What is APIC error CPU0: 00(00)? I know it's really no error (according to the code), but I can't even see how the function gets called in the first place: find -type f | xargs grep smp_error_interrupt ./arch/i386/kernel/apic.c:asmlinkage void smp_error_interrupt(void) ./arch/x86_64/kernel/apic.c:asmlinkage void smp_error_interrupt(void) ./arch/x86_64/kernel/entry.S: apicinterrupt ERROR_APIC_VECTOR,smp_error_interrupt Regards, Nigel -- Nigel Cunningham Pastoral Worker Christian Reformed Church of Tuggeranong PO Box 1004, Tuggeranong, ACT 2901 You see, at just the right time, when we were still powerless, Christ died for the ungodly. -- Romans 5:6 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
