The bigger question is why you get "tons of these" --
as EC events are usually infrequent.
Do you have a big number next to "acpi" in /proc/interrupts?
If so, at what rate is it growing?
maybe tons were a bit to overstated... After a fresh reboot, i count 110
_q10 and one _q21messages now with 8 min. uptime and around 10300 acpi
interrupts.
480 sec/110 ec events = 4 seconds/event. This doesn't worry me.
Could be battery updates, thermal updates etc.
480/10300 = an interrupt every 46 ms.
This is certainly not right.
Have you always seen runaway acpi interrupts on this box, no matter the kernel?
To be honest i didn't care and knew about that this could be an problem
until now. But the biggest part of the acpi interrupts seems to happen
while the first minutes, maybe while booting because with 22 min. uptime
i get these values:
CPU0 CPU1
0: 413784 0 IO-APIC-edge timer
9: 14544 0 IO-APIC-fasteoi acpi
24 min. uptime:
CPU0 CPU1
0: 435875 0 IO-APIC-edge timer
9: 15247 0 IO-APIC-fasteoi acpi
26 min. uptime:
0: 470428 0 IO-APIC-edge timer
9: 16251 0 IO-APIC-fasteoi acpi
So let's say approximatley 700 to 1000 acpi interrupts in 120 seconds. I
guess this sounds better, doesn't it?
