ACPI high interrupt rate with vanilla 2.4.22

ACPI high interrupt rate with vanilla 2.4.22

Hi All,

Today I installed 2.4.22. First thing what I noticed was the very high
interrupt rate on acpi.

After
11:43:53 up 12 min,  0 users,  load average: 0.32, 0.63, 0.39

           CPU0       
  0:      73491    IO-APIC-edge  timer
  1:       3783    IO-APIC-edge  keyboard
  2:          0          XT-PIC  cascade
  8:          2    IO-APIC-edge  rtc
  9:          2    IO-APIC-edge  eth0
 14:        919    IO-APIC-edge  ide0
 15:          9    IO-APIC-edge  ide1
 20:      11779   IO-APIC-level  aic7xxx
 22:   60376810   IO-APIC-level  acpi
NMI:          0 
LOC:      73449 
ERR:          0
MIS:          0

This high interrupt rate slowdowns the box noticeable.

Next problem is that eth0 doesn't work if acpi enabled. See attached
dmesg

When I type pci=noacpi on lilo prompt then I can't boot the machine. It
hangs while detecting the scsi drives on aic7xxx.

So I had to type acpi=off but the machine doesn't poweroff itself:-(

The same problem exists of course with 2.6.0-testX kernels.

Another thing is /proc/acpi/processor/
There are 2 CPU entries...?!?

greets

Marc

RE: ACPI high interrupt rate with vanilla 2.4.22

[Nakajima, Jun]

Is this ASUS P4T533 based system? 

   PCI: No IRQ known for interrupt pin A of device 02:0a.0

   02:0a.0: 3Com PCI 3c905B Cyclone 100baseTx at 0xd800. Vers
LK1.1.18-ac
   00:50:04:07:23:f6, IRQ 9

Looks like the kernel fails to find the PCI interrupt link for the NIC.
Can you send acpidmp of the machine to linux-acpi-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org?

BTW, we realized "pci=noacpi" does not work well. Please "acpi=off" in
the meantime. We are working on the patch.

Thanks,
Jun

Do you have a P4 with the "mulithreading" feature? This appears under 
Linux as a second CPU.

Sorry, I meant hyperthreading, of course.  Please excuse the confusion...

Yes it is, exactly P4T533-C

Attached. Also again dmesg with acpi, and a "good" dmesg without acpi


Thank you

No problem. And no it's not a P4 with HT, but the Board (Asus
P4T533-C) is HT capable. AFAIK every P4 processor has the ht flag...

Your board should be SMP capable.  ACPI describe only what
firmware know about, and some bios will report 2 processors regardless
of the actual number.  Just that the second is not online.

Hi, Marc,

I have opened a tracker # 1165 on bugzilla.kernel.org, Would you please open an account for yourself, and followed upthis issue  there.

Thanks,
Luming

Subject: [ACPI] ACPI high interrupt rate with vanilla 2.4.22


Hi All,

Today I installed 2.4.22. First thing what I noticed was the very high
interrupt rate on acpi.

After
11:43:53 up 12 min,  0 users,  load average: 0.32, 0.63, 0.39

           CPU0       
  0:      73491    IO-APIC-edge  timer
  1:       3783    IO-APIC-edge  keyboard
  2:          0          XT-PIC  cascade
  8:          2    IO-APIC-edge  rtc
  9:          2    IO-APIC-edge  eth0
 14:        919    IO-APIC-edge  ide0
 15:          9    IO-APIC-edge  ide1
 20:      11779   IO-APIC-level  aic7xxx
 22:   60376810   IO-APIC-level  acpi
NMI:          0 
LOC:      73449 
ERR:          0
MIS:          0

This high interrupt rate slowdowns the box noticeable.

Next problem is that eth0 doesn't work if acpi enabled. See attached
dmesg

When I type pci=noacpi on lilo prompt then I can't boot the machine. It
hangs while detecting the scsi drives on aic7xxx.

So I had to type acpi=off but the machine doesn't poweroff itself:-(

The same problem exists of course with 2.6.0-testX kernels.

Another thing is /proc/acpi/processor/
There are 2 CPU entries...?!?

greets

Marc
