The machine is a Dual Xeon running Red Hat Linux release 9 (Shrike) with

The machine also shoots up to a load of about 12 and locks up nightly.
Could this be related?

Let me know if you require any additional information.

Thank you.

APIC error

[Rene Rebe]

Hi,

on a dual Pentium-mmx 233Mhz box (I got for free ...) I get many APIC
errors, like:

APIC error on CPU1: 08(00)
APIC error on CPU0: 02(00)
... ...

I also sometimes got 04(00).

Those errors only seem to happen during high disk-io (SCSI or IDE).
What specific meaning do those errors have? Are they dangerous?

Each CPU survives hours in memtest86 ... And with maxcpus=1 it also
does not seem to happen ... The BIOS is latest.

Sincerely,
  René Rebe

They are defined in Intel's IA32 manual set, volume 3,
"System Programming Guide", downloadable from developer.intel.com.

These errors mean that APIC bus messages are lost or have checksum errors.
You don't say which kernel you're using or which chipset, but chances are
your mobo's APIC bus is noisy.

You can try booting with "noapic", that should let you keep using SMP
while avoiding your possibly buggy APIC bus.

Thanks for the anwer I googled for this before the mail but only found
much noise ... I'll triy noapic (I thought this would disable SMP,
too), but I already had to notice that with maxcpus=1 I also get some
few APIC errors.

Is there drawback in using noapic in SMP mode?

Sincerely,
  René Rebe

No load balancing of I/O interrupts since they will all be directed to
CPU 0 only. Unless your dual P5 is servicing a lot of interrupts, I doubt
it will make a noticeable difference.

On my Dual PII 333, KDE 3.1 runs fine with interrupts mapped to both CPUs,
and performance is horrible when only CPU0 receives the interrupts.

Especially moving the timer interrupt to both CPUs makes difference like
night and day.

Thanks for all your contributions ;-) But with noapic I also get APIC
errors from time to time (altough /etc/intrerrupts shows that the
XT-PIC is used). But anyway the box is not running very reliable in
both modes and processes seg-fault every now and then and sometimes
the box freezed. I'll get rid of the box I got for free and no longer
waste our time ... ;-)

APIC error

[-- Attachment #1: Type: TEXT/PLAIN, Size: 289 bytes --]

Ran across this notice during boot while looking for some other
information.  This is the entire dmesg output , the notice is where it
gives me this email address to send the info to.  Probably a known issue,
thorougly taken care of in the latest kernel but here it is FYI.

APIC error

[Jürgen Braun]

Hi

I've a problem with APIC on my Gigabyte 586DX SMP-System with two P166MMX and Kernel 2.4.18 and 2.4.19-rc3-ac3. When both CPU's are under load (e.g. compiling the Kernel) I get this message in syslog about every 5 - 10 sec:

APIC error on CPUX: YY(ZZ)

X is 0 or 1
YY is 02 or 08 (sometimes 04 or 0a)
ZZ is always 00

After I searched the archive of this list I found the following hints:

"not overclocking"
Well, the CPU's only run with 150MHz to make sure there are no problems with temperature. Or sould I put it in a refrigerator? ;)

Use Bootparameter "noapic" and/or "nmi_watchdog=0"
I tried it with "noapic" with "nmi_watchdog=0" and with both.
Well, this sounds a little bit strange to me, because even if I say "noapic" the error occurred.

I found a hint there could be a problem with the onboard AIC-7880 SCSI.
The error occur with an installation on a SCSI-Disk with IDE disabled and an installation on an IDE-Disk with SCSI disabled.

Nothing helps.

Please give me a hint how to fix this problem. Thanks

Juergen

P.S. I'm not a member of this list.
