Hello,
Usually I ask questions on the mailing lists when things are bad and can't
find much info about the problem myself. This is one of these cases now :)
Recently (started something like a week or two ago) my system which was
running months without any issues spontaneously rebooted. Nothing in the
logs about the reboot.
Then a few days ago it rebooted by itself a few more times, sometimes a 3-4
times a day without a clear reason in the logs of why this happened.
I'm monitoring the CPU temp, load, network traffic and other metrics in the
monitoring system, but there's nothing strange there - no load, no high
temp, no high traffic or anything that could explain why this is happening.
The machine is connected to a UPS, so I thought this could be causing this,
but I've tested the UPS and battery and they are all fine.
Here's what last(1) says about today's reboot:
---
boot time Fri Jan 18 00:29
---
It's like the system has been rebooted normally, but that isn't the case.
Sometimes it's logged as "crash". I've enabled crash dumps, but still
nothing in /var/crash after the failure.
The only error I'm able to find in /var/log/messages during boot-time is
this:
---
Jan 18 11:03:19 tsunami kernel: acpi0: <_ASUS_ Notebook> on motherboard
Jan 18 11:03:19 tsunami kernel: ACPI Error: [RAMB] Namespace lookup
failure, AE_NOT_FOUND (20110527/psargs-392)
Jan 18 11:03:19 tsunami kernel: ACPI Exception: AE_NOT_FOUND, Could not
execute arguments for [RAMW] (Region) (20110527/nsinit-380)
---
Not sure if this is the root cause for this, cause I've seen this error
before and at that time there were no reboots happening (months ago). Also
I find it strange that it says Notebook above, as this is a desktop
machine...
And currently I'm out of ideas. Could you guys give any advice or hints
what else I could check and sort this out?
Thanks and regards,
Marin
