The first problem is that load average is sometimes miscalculated - e.g. now I have this: # uptime 15:53:22 up 11:27, 6 users, load average: 0.97, 1.00, 18446744073708754944.00 (few seconds later) # cat /proc/loadavg 0.82 0.96 657189.15 1/330 2191 Maybe some atomic increments or what are not so atomic? :-) I did not observe the above behaviour under 2.6.8.1. The second problem is the following message I have found today in dmesg(8) output: : irq 11: nobody cared! : : Call Trace: {__report_bad_irq+48} {note_interrupt+87} : {__do_IRQ+257} {default_idle+0} : {do_IRQ+58} {ret_from_intr+0} : {thread_return+41} {default_idle+39} : {cpu_idle+32} : handlers: : [] (acpi_irq+0x0/0x1a) : Disabling IRQ #11 The IRQ 11 is ACPI, according to /proc/interrupts: # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 3562 19705 41402688 148703 IO-APIC-edge timer 1: 0 0 77 0 IO-APIC-edge i8042 8: 0 0 0 0 IO-APIC-edge rtc 11: 2 10 99764 224 IO-APIC-level acpi [...] The ACPI daemon is running, and kacpid kernel thread as well: # ps ax|grep acpid 15 ?
