Hello, |
| 2 |
|
| 3 |
I've just installed Gentoo on a dual-processor machine and now I'm running |
| 4 |
into the following problem - when I start emerge, it randomly stops and one |
| 5 |
of the following things happens: |
| 6 |
- the machine freezes completely so that I cannot switch to another |
| 7 |
console or do anything |
| 8 |
- if I already have multiple ssh sessions open, sometimes one of the |
| 9 |
sessions remains alive, but invoking any command freezes that session. Any |
| 10 |
attempt to kill a process has no effect. |
| 11 |
- soft lockup detected on at least one cpu. |
| 12 |
|
| 13 |
I'm running out of ideas what to try next, so I thought I would ask for |
| 14 |
help. |
| 15 |
Here is what I checked and tried so far: |
| 16 |
- configured and built the kernel with SMP and NUMA support. |
| 17 |
Triple-checked this. |
| 18 |
- both processors are detected and initialized at boot. ACPI is used for |
| 19 |
SMP configuration information |
| 20 |
- processor temperatures: CPU0 32 C, CPU1 31 C, system 39 C. System is |
| 21 |
located in a room with steady 20 C |
| 22 |
- disabled CPU#1using |
| 23 |
echo 0 > /sys/devices/system/cpu/cpu1/online |
| 24 |
In this case, everything seems to work fine. This is the only way to |
| 25 |
compile or emerge anything. |
| 26 |
- using MAKEOPTS="-j3". Tried with "-j2", but the same problem occurs. |
| 27 |
- checked if there are SMP specific USE flags, and the only one I could |
| 28 |
find was for gimp. |
| 29 |
- experimented with different preemption models. The problem occurs with |
| 30 |
all of them. |
| 31 |
- disabled APM and enabled ACPI 2.0 support. After I did this, I've got |
| 32 |
"kernel panic - killing interrupt handler ...." |
| 33 |
|
| 34 |
The system has 2 AMD Opeteron Processors 252, 5 disks - 1IDE Maxtor |
| 35 |
6B200R0 and 4 SCSI Maxtor 6L300S0, and probably irrelevant ATAPI 48X DVD-ROM |
| 36 |
DVD-R CD-R/RW drive, Ethernet controller: Broadcom Corporation NetXtreme |
| 37 |
BCM5703X Gigabit Ethernet (rev 02), RAID bus controller: Silicon Image, Inc. |
| 38 |
SiI 3114 [SATALink/SATARaid] Serial ATA Controller (rev 02), FireWire (IEEE |
| 39 |
1394): Texas Instruments TSB43AB22/A IEEE-1394a-2000 Controller (PHY/Link), |
| 40 |
VGA compatible controller: ATI Technologies Inc RV350 AP [Radeon 9600] |
| 41 |
05:00.1, Display controller: ATI Technologies Inc RV350 AP [Radeon 9600] |
| 42 |
(Secondary). |
| 43 |
Kernel version is 2.6.17 built using gentoo-sources. |
| 44 |
|
| 45 |
Any idea what might be causing this problem? Bad kernel configuration? Bad |
| 46 |
system configuration? Kernel bug? Portage bug? Defective processor? Problem |
| 47 |
with disk access? |
| 48 |
I'm including a snapshot of the info I could retrieve from the system when |
| 49 |
the system remained somewhat responsive after the problem occurred. |
| 50 |
|
| 51 |
Kind regards, |
| 52 |
Vesna |
