(Cc:ing Andi because I seem to remember him reworking the code for this chipset)
Got it. After a suspend/resume cycle, I no longer have any timer ticks. Unsurprisingly, this breaks things. This is even true if I stub out the actual suspend code - that is, simply calling the device suspend and resume methods fails to set up the timer again properly.
So the situation is the following: without acpi_skip_timer_override, the system works fine until suspend/resume. At that point, I no longer get any timer ticks. With acpi_skip_timer_override, the timer works fine before and after suspend. I suspect that something in the apic suspend/resume code isn't setting things correctly? Is there any useful debug output I can provide? -- Matthew Garrett | mjg59@srcf.ucam.org - 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/
