IPMI-SEL says System Event #0:System Reconfigured, but no actual changes made

[Won De Erick]

Is there any significant of the following? 

#dmesg
.....
bce1: link state changed to DOWN
bce1: link state changed to UP

....
Can this result into the significant log on SEL?

Hi All,

On IBMx3650 (IPMIv2.0-compliant), running FreeBSD6.2.

I noticed that my system is halting services for around 4-5 minutes, without sufficient logs on the system (system.log) that can bring me to the right conclusion (whether caused by unexpected reboots, etc).

I then retrieved the system event logs (SEL) from the baseboard chip using FreeIPMI v0.6.3, and noticed for multiple "System Event #0:System Reconfigured" logs. 

The latest would be
"54:23-Jan-2009 11:28:55:System Event #0:System Reconfigured"

This is somewhat weird, as I did NOT change any in the system (BIOS, OS, BMC firmware, etc.) This is the cause of service halts as verified though my mrtg, and the system uptime.

I usually get logs like the following (e.g. only) when such unresponsiveness is due to watchdog triggering, 

24-Jan-2009 17:09:30:Watchdog 2 Watchdog:Hard Reset
OEM defined = 00 00 
00 00 00 E3 25 86 80 00 00 FF 00

or is simply due to manual/unexpected reboot ("init 0"/kernel panic):
OEM defined = 00 00 
00 00 00 E3 25 86 80 00 00 FF 00

With these, I suspect that the unresponsiveness of the system is not caused by a REAL reboot. Is there any possibily that the system's uptime can be changed even without restarting the box? What does that "system event #0;system reconfigured" mean? Is this related to SMM switching? by an attacker?

Thanks,

Won
