 Posted: Fri Jul 29, 2005 10:46 am Post subject: Opteron smp system stalls. |
 |
|
Hi.
I have this setup:
2x Opteron 244
Tyan K8W board
512mb Transcend ECC/REG DDR memory (additional 1½GB on the way)
Albatron nVidia ti4200 card.
Intel 100pro NIC
and a Western Digital Raptor 74gb drive.
This set have been working perfectly before, but for a short periode of time i needed to run XP so i trashed my gentoo install. NOW im trying to setup my gentoo system again and the install goes perfectly, i use the 2005.0 AMD64 disk.
My compile flags are:
CFLAGS = "-march=athlon64 -02 -pipe"
USE FLAGS are =" X gtk gnome alsa cdr mplayer mepg divx mysql apache"
(need more info?)
The problem is when im trying to emerge so packages that in the middel of the compile the system stalls on the packge. Its not locked, but that process is just going no further. The rest of the system is working fine, but in top i can see the process and i takes 100% of one of the cpu's.
My logs dosnt shows anything new.
So any ideas how to solve this problem? |

this is a little weird.
I have in the BIOS set all settings to failsafe og and know i just seems to run pefectly.
I hope this is all, it such a shame is this system isnt running.

Do you have something like famd running? I know way back in the midsts of time this did cause me a few hiccups.

Nope it didnt fix the problemer after all.
So anyone has a solution or idea?
Perhaps some kernel settings? |

| What kernel version are you running? I have observed similar behavior sporadically on my Opteron 246 box running 2.6.12. Under 2.6.11, I have no problems. |

Now with bios settings in performance mode and the new (old) kernel 2.6.11.11 i have had my system compiling KDE apps for 3-4 hours and there is no sign of the problem. Normaly i would have occured longe ago, so im hoping that all it took was a kernel upgrade.
Thanks joaander |

This *could* be related to this post, and you somehow entered an infinite loop rather than a segfault. Could you please try 2.6.12 again, but do this first as root:
sysctl kernel.randomize_va_space=0
If you want to make it permanent, you can place this in /etc/sysctl.conf:
kernel.randomize_va_space=0

Oh this seems to do the trick to. So its "just" an infinite loop bug in the kernel or?
Anyway im now running with the 2.6.12 and no problems. |

No, it's not an infinite loop in the kernel. It's a bit more complicated than that. Check out the bug report listed in the forum post I reference above if you want the full details, or if youu don't really are and only want something that works, leave that line in sysctl.conf, and take it out occassionally to test in newer kernels until the bug gets squashed.
