After inserting a kernel module I wrote and trying to read the device it created, I see the following in dmesg: Losing some ticks... checking if CPU frequency changed. warning: many lost ticks. Your time source seems to be instable or some driver is hogging interupts rip tg3_read32+0x9/0xa [tg3] Falling back to HPET APIC error on CPU3: 00(80) APIC error on CPU3: 80(80) where the last message was repeated 1600 times. Could anyone tell me what it means or of a better place to ask about it? Thank you, Timur
