Slackware 14.2 total lockup even reboot button is stuck (hardware related?)


Hi all. Sometimes I get Slackware 14.2 total lockup even reboot button is stuck.
No keyboard, no mouse actions at all. Animations are stuck on screen too.
I had one just minutes ago.
I believe it might be hardware related problem.
How I can investigate such problem?
Some log files?
I can post all info you need for following investigation.

If you have in local network some other machine you can use netconsole (i.e. see https://www.kernel.org/doc/Documenta...netconsole.txt ). It can be used to log kernel messages to other computer even if they not show up on screen or save in local syslog.

You can also test your RAM by memtest ( https://www.memtest86.com ) or CPU by torture test in prime95 ( https://www.mersenne.org/download/ ).

I tired memtest not so long time ago, so I decided prime95. And it stops running after very short time:

Similar result with "Type of torture test to run (3): 2", but not with first one.
So bad memory controller?

Not necessary, in modern computers memory controller is embedded in CPU...

You can also test:
1. If you have removable memory modules, and more than one installed, you can try to remove one or more and repeat the torture test.
2. Check CPU temperature during torture test ( i.e. on other console run "watch -n 1 sensors" ).
3. In desktop computer, if you own multimeter, you can also check voltages for level and stability. Test black cables (ground) with yellow (~12V) red (~5V) and orange (~3.3V) ones.
Black, red and yellow can be easy find in MOLEX, or SATA power plugs. Orange is only available in main board plug. But be VERY careful, and don't make any short circut!. Best do this also during the torture test.
4. When you have open computer, you can also inspect main board for fries, or bad looking capacitor (leaked, swolen) especially near CPU socket.
5. If possible check other power supplies, CPU, and mainboard.

Hi.

I don't know what kernel version are you using, but I hope you can fix your problem.

Long time ago I used to have a pc hard freeze using recent generic kernels, (by some weird reason the generic kernels from 4.9 and up numbers), and checked my hardware with no luck, but I found that my pc works very good with generic kernels 4.4.x and low latency kernels.

Hope you can find and fix your problem.

Cheers.

Will the system run with BIOS/UEFI Defaults loaded? Does it, or has it ever, run hot?

If it was a desktop PC I'd be inclined to suspect the power supply unit. Power delivery around the system by the motherboard is also a possible culprit, in both desktop and laptop computers. The first easy to diagnose, the second not.

Wow thanks for so many advises. I will try to use them one after other. It is desktop PC with extra big CPU fan. BIOS set to all quite default.
I already checked temperature CPU core.
CPU temp. at test start like 55*C (already used PC) it jumps to 62*C quite fast and during failure moment reaches something like 64*C.
Quite old Q9300 I have.
Also it has pack of 4*2Gb RAM stacked into all motherboard slots.

Your video card can also be overheating or going bad, but as one who's been using and building my own since '98, I'd suspect first an overheating problem somewhere, next would be a tie between the power supply and the video card (if there is one and not built into the MOBO or CPU). Those are first and foremost the easiest to check...at least they are if you have spare parts to try out with.

Just because the CPU heatsink has a whopping big fan, doesn't mean it's not doing something correctly. Do you blow out the fins regularly? If they get clogged up with dust, the heatsink is useless and becomes a heat absorber/holder. Get a can of compressed air at your local Chinamart (Walmart) or wherever and blow the insides of your system out...get two cans as they don't last all too long.

Give that a try, *then* futz with the BIOS settings.
