[uml-devel] skas v8.2 results

[Peter]

Hi.

We tried 2.6.12.3-skas3-v8.2 on a host server.  It kernel paniced (could 
not capture the panic) after about 90 minutes.  I'd tried a 2.6.12 
skasv8.2 a week or so back on another server and got the same result.


2.6.11.12-skas3-v8.2 has been running fine for 20 odd hours.

Has anyone had success with 2.6.12 skas v8.2?  If so I'd be interested 
in a kernel .config.  FWIW our hosts are dual xeons.

Regards, Peter

Peter,

I haven't tried 2.6.12. However, I'm now testing v8.2 with 2.6.13-rc4 on one
of our development machines. It's been running for 16 hours without issue.
This is a dual Opteron system running a 32-bit kernel. Have you tried a
vanilla 2.6.12.3 kernel to determine if the issue is with SKAS?

Tony

I had a similar problem a few weeks back when I attempted to run 
2.6.12.1 and skas-2.6.12-rc4-v9-pre4.  Crashed within 30 minutes or so, 
so I reverted back to 2.6.11.11 and skas-v8.  I haven't had the time to 
narrow down the problem.  It's on my to-do list for this week.

Incidentally, I've had kernel stability problems with the last dozen 
hosts I've placed online.  These machines crash with no console output 
after a few days to a few weeks uptime.  Haven't been able to track it 
down yet, but my hope is whatever it might be is fixed in more recent 
kernels.  It seems like a hardware or CPU speed and kernel version 
issue, since the identical kernel runs flawlessly on other, slower hosts.

I'll post more details in a few days.

Peter, has anything changed on this issue? Had problems with 2.6.11 or success 
with 2.6.12/2.6.13?

I've not heard any news, plus I've difficulties in imagining what's wrong 
here. However, I'm going to think a bit more on this, and on an idea I just 
had.

Hi.  We have not re-tried a skas kernel later than 2.6.11.
