Good Evening,



I have a problem with CentOS 6.2.

On December 2011 I installed CentOS 6.1 on a HP ProLiant DL 165 G7

server.

Recentely I upgraded to CentOS 6.2 but at reboot the system didn't

startup. So I removed new kernel kernel-2.6.32-220.4.2.el6 and CentOS

was again able to startup with original kernel-2.6.32-71.el6.x86_64. But

now every two days the system automatically reboots as you can see

below:



reboot system boot 2.6.32-71.el6.x8 Wed Feb 22 22:53 - 17:10

(18:16)

reboot system boot 2.6.32-71.el6.x8 Wed Feb 22 20:04 - 17:10

(21:06)

reboot system boot 2.6.32-71.el6.x8 Fri Feb 17 22:55 - 17:10 (5

+18:14)

reboot system boot 2.6.32-71.el6.x8 Fri Feb 17 07:05 - 17:10 (6

+10:04)

reboot system boot 2.6.32-71.el6.x8 Wed Feb 15 15:02 - 17:10 (8

+02:08)

reboot system boot 2.6.32-71.el6.x8 Mon Feb 13 00:33 - 17:10 (10

+16:36)

reboot system boot 2.6.32-71.el6.x8 Sun Feb 12 16:08 - 17:10 (11

+01:02)

reboot system boot 2.6.32-71.el6.x8 Sun Feb 12 15:00 - 17:10 (11

+02:09)

reboot system boot 2.6.32-71.el6.x8 Thu Feb 9 18:06 - 17:10 (13

+23:03)

reboot system boot 2.6.32-71.el6.x8 Tue Feb 7 01:22 - 17:10 (16

+15:47)





In log file /var/log/messages there are no particular events happened

before system halt down.

Have you some idea of how I can resolve these problems? Do you think

they are correlated?

Thank you for the attention.

You say the system didn't come up - how far did it get? How did you remove
the newer kernel?

Personally, I'm moving as fast as I can to get *rid* of the 220.2 kernel,
with its constant, irregular crash dumps with traces that all start with
warn_slowpath.

Is the server on a UPS?

Looks to me as though its randomly rebooting several times a day. I'd
seriously wonder about hardware or power problems.

I was wondering about something like that. A friend mentioned, on another
list, about how some idiot had plugged, um, don't remember, coffee pot?
microwave? into a power outlet that was orange, and labelled "computer
equipment only". After he had to come in (he's a consultant) and $fix$ the
resulting mess, it may have gotten through to the staff.

I am unable to run anything later then
2.6.32-220.2.1.el6.centos.plus.x86_64. Booting of 220.4.x just hangs. I
had no time to file a bug report, always something more pressing. But
will do it soon. 220.2.1 runs without a problem for weeks at the time
(always-on desktop).

Out of curiosity, why CentOS plus, and not the std.?

Past experience with 5.x is that additional kernel modules can come in
handy. Also there were always some optimizations or things that are
disabled by the upstream.

Regular 220.4.x kernel was first installed, but no dice with it. Then I
tried 220.4.x centosplus and still no dice.
