Bug 129892 – 2.6.15-r7 kernel not stable , don't know what's wrong , use 2.6.16-5 just ok.

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description wangyong 2006-04-13 18:57:11 UTC]

i build a system as a router (plus nat using iptables) for a big network (about 6000 endpoint).

when i use 2.6.15-r7 , the kernel always crash.  so i switch to 2.6.16-5. it's ok. 

hoping for changing the kernel.

Don't restrict bugs without any reason, please. 

There's no real information here. When does the crash occur? Anything interesting in the kernel log? Or screen output? Kernel .config? emerge --info? We can't guess, sorry.

sorry for not giving real information. cause i just build a base gentoo ( from 2006.0 handbook for amd64, no special).
 
emerge  --info

using /usr/share/genkernel/x86_64/kernel-config-2.6 as default .config. (genkernel 3.3.11
&& genkernel all) 

patch kernel with patch-o-matic-ng-20060409 for iptables.
just adjust the netfilter options. 

using genkernel builds the two kernel. ( 2.6.15-r7 and 2.6.16.5). just the same .config and same env. 

cause the system will be used as soon as i can . so i don't have time to record the crash information.

so that's all.

Reopen.

Theres absolutely no information here about the crash. We can't help you unless you provide details.

cause the system has being used . so i just rebuild another system to find the problem.( same machine,same env) i think that it may be a  'apic' problem. 
it's the common problem in the 2.6 series kernel.

sorry for disturbing you.

here i got some userful information.
First boot from common kernel options.

Get crash information as below.

PID 0, comm: swapper not tainted 2.6.15-gentoo-r7 #1
RIP:0010:[<00000000000>][<00000000000>]
RSP:0018:ffffffff803be4a0 EFLAGS:00010202
....
Code:BAD RIP VALUE
<0>kernel panic - not syncing:Aiee,killing interrupt handler! 

Later i use "acpi=off noapic noirbdebug" for this kernel to boot,  it will show nothing and just dead.
