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? thanks, -Len
