Justin, No I did not use noapic initially.
I just tried and got the /proc/interrupts hereafter, which still gives me qhal_host and i915 on the same line (IRQ 9) Would your fix be to enable the CONFIG_PCI_MSI kernel option? I tried it already and it made no difference. Unlike your 965 system, my 945 system doesn't support MSI (see comment in i915_driver_load () from drivers/gpu/drm/i915/i915_dma.c) :( CPU0 CPU1 0: 35 0 XT-PIC-XT timer 1: 2 0 XT-PIC-XT i8042 2: 0 0 XT-PIC-XT cascade 3: 2 0 XT-PIC-XT 4: 11 0 XT-PIC-XT 5: 2 0 XT-PIC-XT 7: 826 0 XT-PIC-XT 9: 7938 0 XT-PIC-XT acpi, qhal_host, i...@pci:0000:00:02.0 10: 2 0 XT-PIC-XT 14: 3872 0 XT-PIC-XT ide0 28: 147 0 PCI-MSI-edge eth0 30: 0 0 PCI-MSI-edge ahci NMI: 0 0 Non-maskable interrupts LOC: 14233 14220 Local timer interrupts RES: 767 456 Rescheduling interrupts CAL: 18 40 Function call interrupts TLB: 339 255 TLB shootdowns TRM: 0 0 Thermal event interrupts SPU: 0 0 Spurious interrupts ERR: 826 MIS: 0 Hugo.
