Hi all,
I have two problems with my HP DL585 quad Opteron running 2.6.10-rc2. 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:<IRQ> <ffffffff8014f3b0>{__report_bad_irq+48} <ffffffff8014f477>{note_interrupt+87} : <ffffffff8014edb1>{__do_IRQ+257} <ffffffff8010b2a0>{default_idle+0} : <ffffffff801100ea>{do_IRQ+58} <ffffffff8010d71d>{ret_from_intr+0} : <EOI> <ffffffff804014b9>{thread_return+41} <ffffffff8010b2c7>{default_idle+39} : <ffffffff8010b350>{cpu_idle+32} : handlers: : [<ffffffff80299e15>] (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 ? SW< 0:00 [kacpid] 17462 ? S 0:00 /usr/sbin/acpid
