[App_rpt-users] kernel panic in the cold

[Chris Curtis]

Thanks for all the input.
After running 24 hours in the house without a hitch, I'm going to go with sub freezing temperatures as the culprit.

I realize I didn't put enough background in my post so here's a little more in case it'll help someone else.

Box:
Regular old hand me down desktop in a mini tower case. The acid/cent distro from the website link.
Old single core processor with HT enabled
Traditional spinning platter hard drive (SATA interface)
DDR2 ram
3 modified cm108 fobs

Shed:
Lowest temperature so far 9F
Averaging around 33F for the problem period

Why didn't I think of this before:
Last system I owned/operated was a 3 band repeater with an irlp node onsite.  The controller was an ff-800.
Only trouble I had in that non climate controlled shack was the ff-800 needed a warming pad draped over the cabinet in the winter.
The irlp node/pc never gave me any trouble but the ff-800 would 'talk funny' when it got really cold.

Should have remembered this earlier.
Again, thanks for the replies, I appreciate it.
Just like the well pumphouse, I'll put an incandescent light bulb near the box/fobs and try that.

Chris,

If this turns out to be the problem, let me know. I have made many options for such a winter occasion.
But be sure to check the cpu reporting of temp to bios and OS. Normally, they are meant to look for overheating not under-heating. But I have problems with the thermistor being out of intended range and that created a problem (disable temp mon in bios).
Many low power electronics/cpu's do not function well at sub freezing temps including the sound dongles.

It's cold out in the shed.
No climate control at all.

Could this be the culprit of my almost immediate kernel panic lockups ?
Server/nodes had been running fine over the summer.

I've brought the box inside the house and will run it with the dongles
attached to see if some heat will fix the problem.

Just wondering if anyone else had been experiencing:
"kernel panic not synching fatal exception in interrupt";
these past months.

Thanks for your time,
