Hello,
I've just installed Gentoo on a dual-processor machine and now I'm running
into the following problem - when I start emerge, it randomly stops and one
of the following things happens:
- the machine freezes completely so that I cannot switch to another
console or do anything
- if I already have multiple ssh sessions open, sometimes one of the
sessions remains alive, but invoking any command freezes that session. Any
attempt to kill a process has no effect.
- soft lockup detected on at least one cpu.
I'm running out of ideas what to try next, so I thought I would ask for
help.
Here is what I checked and tried so far:
- configured and built the kernel with SMP and NUMA support.
Triple-checked this.
- both processors are detected and initialized at boot. ACPI is used for
SMP configuration information
- processor temperatures: CPU0 32 C, CPU1 31 C, system 39 C. System is
located in a room with steady 20 C
- disabled CPU#1using
echo 0 > /sys/devices/system/cpu/cpu1/online
In this case, everything seems to work fine. This is the only way to
compile or emerge anything.
- using MAKEOPTS="-j3". Tried with "-j2", but the same problem occurs.
- checked if there are SMP specific USE flags, and the only one I could
find was for gimp.
- experimented with different preemption models. The problem occurs with
all of them.
- disabled APM and enabled ACPI 2.0 support. After I did this, I've got
"kernel panic - killing interrupt handler ...."
The system has 2 AMD Opeteron Processors 252, 5 disks - 1IDE Maxtor
6B200R0 and 4 SCSI Maxtor 6L300S0, and probably irrelevant ATAPI 48X DVD-ROM
DVD-R CD-R/RW drive, Ethernet controller: Broadcom Corporation NetXtreme
BCM5703X Gigabit Ethernet (rev 02), RAID bus controller: Silicon Image, Inc.
SiI 3114 [SATALink/SATARaid] Serial ATA Controller (rev 02), FireWire (IEEE
1394): Texas Instruments TSB43AB22/A IEEE-1394a-2000 Controller (PHY/Link),
VGA compatible controller: ATI Technologies Inc RV350 AP [Radeon 9600]
05:00.1, Display controller: ATI Technologies Inc RV350 AP [Radeon 9600]
(Secondary).
Kernel version is 2.6.17 built using gentoo-sources.
Any idea what might be causing this problem? Bad kernel configuration? Bad
system configuration? Kernel bug? Portage bug? Defective processor? Problem
with disk access?
I'm including a snapshot of the info I could retrieve from the system when
the system remained somewhat responsive after the problem occurred.
Kind regards,
Vesna

First try swapping around the memory modules. If the system
exhibits the exact same pattern, then swap the cpus.
My guess is one of the low memory modules - below or at 1 GB, is flakey
or that the memory controller on one of the cpus, probably cpu 0, has
an issue.
Another thing to try is if you're running with 4-DIMMs per cpu, downgrade
to 2 DIMMS per cpu.

I have but a few possibilities to suggest, but I can say I've been using a
similar system since late 2003, upgrading it over time, and know it works.
FWIW, Tyan s2885 mobo here, dual Opteron 242s, four-way SATA RAID on SiI
3114 SATA controller, 8 gig memory, Firewire, Radeon 9200 (so the ATI r200
series not the r300 series you have, mine is AGP), a DVDRW, CDRW, and older
PATA hard drive on PATA, etc.
Possibilities:
I had bum memory for awhile. Twas a mess, until I got a BIOS upgrade that
allowed me to declock it a notch (to pc3000 level from the pc3200 it was
rated). A memory upgrade cured that.
The usual possible hardware suspects including the power supply train
(from the one in the computer itself, to what's coming in on the line, to
the UPS if any), and possibly overclocked CPUs. With all those hard
drives, it's possible you are simply underpowered. I think I'm running a
550 watt rated Vantec that's rated to 650-ish spike.
At one point there was an issue with the firewire driver and x86_64 SMP.
Since I'm not using Firewire for anything here, IIRC I disabled it in BIOS
as well as the kernel driver for it. I've not followed up but I'd /guess/
the problem is fixed by now. Still, it's worth trying that, and disabling
any other stuff (like USB possibly in a server environment, which it seems
you are in) you don't actually use.
Those are all shots in the dark, but this is mainly to say that what I
have here seems to work very well, at least since I fixed the memory
issue, which was simply generic memory not worth its rating and an
inability at the time to declock it in BIOS.
