Hello,
I received the following boot message on several Supermicro motherboards
(P4DC6+, P4DCE+, P4DP6) which have among them two Intel chipsets
(860, E7500) when using both RedHat 7.1 and RedHat 7.2.
<<<
WARNING: unexpected IO-APIC, please mail
to linux-smp@vger.kernel.org
>>>
Results for RedHat 7.2 are attached for four of the PCs.
Would this be related to the observation that on all machines
all interrupts go to CPU0 and none go to CPU1?
(We do a "cat /proc/interrupts" to see this.)
My colleagues using dual-CPU Tyan motherboards (Athlon?)
do not see this, and for slightly slower machines they
get slightly faster performance.
Five dmesg logs for four machines are attached.
All four have:
dual Pentium IV Xeon 1.8GHz processors
Supermicro motherboards
RedHat Linux 7.2 with the included 2.4.7-10smp kernel.
except as noted below.
Intel SuperMicro
Machine Chipset Motherboard
"dfd01" 860 P4DC6+ (SCSI on-board but not used)
"dfe01" 860 P4DC6+ (SCSI on-board but not used)
"dfe02" 860 P4DCE+ (no SCSI on-board; else same as P4DC6+)
"dfd02" E7500 P4DP6 (SCSI on-board but not used)
The dmesg log for the enterprise kernel is included for dfd02.
Thank you,

I have a number of these mother boards with 1.7GZ cpus in them. They all have the
"all interrupts in cpu0" problem but there is a patch that I tried with success for
this. It is an irq_balance patch. Don't remember where it came from. Only thing with
it was, once you apply it you can no longer bind an irq to a particular processor if
you want to. I had to back it out because my app and the pci card we are developing,
requires me to bind a process/threads and the irq of the pci card to 1 processor and
force all other processes and all other irq to all other cpu's. It's a emulation of an
old proprietary Real-Time OS and the card is a pci card with 6 high-res timers and 8
external interrupts. The only way to get good interrupt latency/determism numbers is
to do the above. With this patch I could no longer set the irq's to the processor I wanted. When not running the "app" I wanted irq balancing accross the cpu's. It worked ok for that.
It's below and applies to 2.4.18.
Your other problem I don't see at all and the MPS is even set to 1.4 on all my boards bios.
You should probably try setting it to 1.1 and see if it helps.

Dave,
This message has nothing to do with the your performance problems or why
all interrupts go to one CPU.
This message is for the ACPI (IO-APIC included) maintainers to keep an eye
on when there is new hardware.
You should make sure that your MPS setting is set to 1.1 not 1.4 (BIOS option).
Also boot without passing the noapic option to the kernel. This option
causes all interrupts go to CPU0 (bypassing the new 2.4 ACPI stuff).
I have not seen posts related to the Supermicro boards so I don't have a
lot of faith in the above suggestions. But if it doesn't work you should
try disabling everything in the BIOS except for what is needed and try
testing from there.
Anyone else have experience with these boards that can give Dave a hand?
Good Luck,
Earle

Hi,
This particular IO APIC version and flag are handled
(recognized) in 2.4.16 IIRC (maybe 2.4.17).
We are seeing lots of these reports with VIA KT266 or KT333
chipsets (and their IO APICs) with IO APIC version 0x02.
Since VIA doesn't release their chipset specs, we don't know
how correct these are.
And since these are fairly new, code to recognize these hasn't
been added to the kernel yet.

I got this information from multiple sources including Alan and IBM.
However, on at least some Netfinity models (8658 for sure) and BIOS
revisions (12? anyway latest as of June 1 2002) this causes the kernel to
spend most of an hours diddling the onboard SCSI, then getting a lockup.
I've tried this on other Netfinity and it has never fixed anything, so I
don't do it. YMMV.

Alan and others do not agree. I have been using noapic and having
stability, on Netfinity, BP6, and Intel boards. If you see lockups or
other problems under heavy load, try noapic, the performance hit is lower
than I can measure, certainly lower than a solid lockup.
