[SOLVED] Sudden "general protection fault" on Slackware64 14.0

elesmod · 09-21-2013, 08:00 PM

I was playing around in the CLI when suddenly all of my 3 xterm windows got spammed with some kernel messages. Luckily Slackware did not crash

System: Slackware64 14.0 (multilib)
Kernel: 3.2.45

Here's the syslog:

Code:

edit: irrelevant, hardware issue

The only unusual thing my system was doing was running a script which was downloading videos from youtube. I'm a noob when it comes to this stuff, so maybe I've written something that made that "general protection fault"? I'm attaching the script as well.

Code:

But the script did it's job and I have the videos on my HDD

Do you think I should try to post this stuff elsewhere (some kernel.org forum/bugzilla)?

How is your free disk space?

A quick comment on your script. There is an unnecessary use of 'cat'. This construction is preferred.

Code:

while read LINE
do
 ...
done < $FILE

(Thanks for the comment about cat.)

Disk space? That was the first thing I've checked right after it appeared.

Code:

Out of that list only /mnt/win is low on space, but still 880M left, besides, it's a Windows partition.

Also looks good; and swap wasn't used at all.

I was about to go to sleep and wanted to suspend my machine and now I'm starting to see ramifications.
I cannot put my PC to sleep.
When I issue the sync command, it hangs.
There are a lot of processes which I cannot kill -9. I've tried all the 5 digit ones and most cannot be taken down.

1.Power Supply caused interference.
2.Check your motherboard for bloated capacitors.

I suggest a reboot.

Searching for "kswapd0 general protection fault" seems to return results about ram becoming faulty. Can you test your ram with memtest86+?

Yep, it's definately a hardware issue. After switching off my PC, I cannot turn it back on.

Thanks for your replies, guys. I'm marking this as solved and going to look inside my box.

Just an update.

After taking apart my computer, checking the capacitors, thoroughly cleaning (removed the case from PSU too), reapplying thermal paste on CPU and piecing my PC back together, I've been running memtest86 for several hours. So far no errors. I'll stop it after 2nd pass completes.

Hopefully it was nothing more than some dust getting between sockets
