The machine has a broken ACPI but OS doesn't catch it before r243764, and the broken ACPI doesn't make any ill effect. After r243764, OS catch the broken information and treat it as a correct information, so that the machine stops. It is a story I understand from your mail. > o cpuset -l 1 -x 9 -- to try to see what happens if SCI/IRQ9 > is delivered to the AP instead of BSP I cannot find any effect from `cpuset -l 1 -x 9` command. With pure head + your acpi.c patch, the machine can wake up from sleep. But "irq9: acpi0" rate showed by "vmstat -i" is increasing every second after resume. To close and open LCD makes 2 irq9 before resume, but irq9 rate is too fast after resume. "vmstat -i" shows -- before sleep -- interrupt total rate irq1: atkbd0 1153 2 irq9: acpi0 56 0 irq12: psm0 75744 177 irq20: hpet0 30065 70 irq23: ehci1 uhci1 83 0 irq256: ahci0 4572 10 irq258: hdac0 93 0 irq259: vgapci0 1022 2 Total 112788 264 -- after wake up from sleep -- interrupt total rate irq1: atkbd0 1427 2 irq9: acpi0 2364611 4564 irq12: psm0 78870 152 irq20: hpet0 42270 81 irq23: ehci1 uhci1 166 0 irq256: ahci0 4740 9 irq258: hdac0 99 0 irq259: vgapci0 1615 3 Total 2493798 4814 -- after resume and some times later -- interrupt total rate irq1: atkbd0 1643 0 irq9: acpi0 103768672 45313 irq12: psm0 86056 37 irq20: hpet0 442586 193 irq23: ehci1 uhci1 166 0 irq256: ahci0 4942 2 irq258: hdac0 99 0 irq259: vgapci0 3091 1 irq260: alc0 42 0 Total 104307297 45549 -- kaho@elam.kais.kyoto-u.ac.jp
