History: I have been trying to tie-down a strange problem on my headless AMD64 box - it occasionally just turns-off if just as if the power supply is cut. It can happen anywhere between 2 months or 2 days - just intermittent. Analysing logs (which when this occurs they do not report anything), I noticed this in syslog (typical): Dec 28 09:37:19 sauron kernel: ACPI: PCI Interrupt Link [APCL] enabled at IRQ 22 Dec 28 09:37:19 sauron kernel: ACPI: PCI Interrupt Link [APC5] enabled at IRQ 16 Dec 28 09:37:19 sauron kernel: 1030 Dec 28 09:37:19 sauron kernel: 0200 Dec 28 09:37:19 sauron kernel: 0110 Dec 28 09:37:19 sauron kernel: 0111 Dec 28 09:37:19 sauron kernel: 0113 Dec 28 09:37:19 sauron kernel: 0362 Dec 28 09:37:19 sauron kernel: ACPI: PCI Interrupt Link [APSI] enabled at IRQ 21 Dec 28 09:37:19 sauron kernel: ACPI: PCI Interrupt Link [APSJ] enabled at IRQ 20 I don't understand what the middle lines are telling me here? Anyway, today I took the machine down, and removed ram a module (as I found it's sister slot was bad) and also the graphics card as I don't use it. Now when I boot, these mysterious line have vanished from syslog: ec 29 13:05:49 sauron kernel: ACPI: Enabled 1 GPEs in block 00 to 1F Dec 29 13:05:49 sauron kernel: ACPI: PCI Interrupt Link [APCF] enabled at IRQ 23 Dec 29 13:05:49 sauron kernel: ACPI: PCI Interrupt Link [APCL] enabled at IRQ 22 Dec 29 13:05:49 sauron kernel: ACPI: PCI Interrupt Link [APSI] enabled at IRQ 21 Dec 29 13:05:49 sauron kernel: ACPI: PCI Interrupt Link [APSJ] enabled at IRQ 20 Dec 29 13:05:49 sauron kernel: ACPI: PCI Interrupt Link [APCH] enabled at IRQ 23 is all I get now in that section. Was the kernel attempting to tell me something was bad with them funny unnamed lines?
