Subject: 2.6.10-rc2 x86_64 SMP problems
Date: Mon, 29 Nov 2004 16:01:55 +0100 [thread overview]
Message-ID: <20041129150155.GC24911@fi.muni.cz> (raw)
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}

: 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
