Charles,
Even if APMD is not running, a specific apmd bios
setting could definitely affect -Linux boxes used
to reboot unexpectedly when power management set
the machine to sleep back in the times when APMD
did not exist.
My advice is to check all relevant bios settings,
including:
- unusual interrupt settings.
- power management 'toys'. There is no need for
them if yours is a 365/24/7 server.
- aggressive settings: raw-access-anything,
video optimisations, etc.
Write down your current set up and work from
there. I think you will probably find something
that triggers the problem.

Subject: Re: [Help] Strange Linux server no
response problem, fixed byhitting ENTER at console!
Dear All,
Thank you for your suggestions.
No, apmd is not running at the server, but if APM
is turned on at the BIOS will it have any
effects? (I have to goto check it)
Actually the problem does not happens everyday,
so I'm not sure if it is related to power
management issue.
CPU usage is quite normal, at least always has
IDLE cpu time. As of now in top:
3:56pm up 9 days, 2:35, 1 user, load
average: 0.91, 1.09, 1.38
120 processes: 119 sleeping, 1 running, 0 zombie,
0 stopped
CPU0 states: 19.0% user, 18.0% system, 0.0%
nice, 62.0% idle
CPU1 states: 11.0% user, 8.0% system, 0.0%
nice, 80.0% idle
Mem: 642740K av, 514852K used, 127888K free,
0K shrd, 53480K buff
Swap: 530040K av, 91420K used, 438620K free
282576K cached
Actually the server has strange "no response"
problem for over half year for a few times
already, I just discovered I can "fix" it with
"ENTER" key at the console login screen recently.
If it looks like interrupt problem, I may try to
find hardware to replace it and give it a try.
btw, will a IDE Software RAID-1 create this
problem? (both disks running UltraDMA mode already)
Motherboard is ASUS P2B-D, Dual P3-700Mhz Slot-1
Best Regards,
Charles
