System freezes

[DisappearingOak]

Hello. I'm having a freezing issue with PCLOS where the system locks up, mouse is frozen and Num Lock unresponsive although I can REISUO to shut down the system. I've collected logs on the subsequent boot and hope someone here can help me find out the cause of the problem. Much appreciated, thansk.

Please post more info of the system and what version of pclinux you use

What kernel do you have?  uname -r in console

Have you verified you pc?  Clean it and verify temperatures?

In the end of that log it mentions something suggesting that you need to do a fsck

Hello, system is AMD 3.4 Ghz quad, 4Gb Ram, Amd 880G chipset (Radeon hd 4250 graphics). I'm on PCLOS lxde mini with stock kernel, fully updated. uname -r  3.2.18-pclos2.bfs

My PC is clean, was cleaned of dust just a few days ago. Temps are ok, also. I had measured temps a couple months ago in another thread for another issue, they were alright then, and now also.

What exactly do I need to do? Is fsck a disk check? Also, I have logs saved including Xorg log, dmesg, messages. If required, I can post them also. Thanks

fsck is a command to verify the partitions, i never ran it so can't guide you here, there is some posts on this forum explaining the process

from the little i remember on those posts i think that most used the livecd and when the partitions were unmounted, the command could be used to fix errors

Why do you keep a Kingston Datatraveler plugged in permanently? It's generally better to plug in USB/SD sticks when needed on a system that's already running.

You have 30 GB of swap! That seems like an awful lot.

You need a PAE kernel to use all your memory which might be important as you appear to have tmpfs set up (clean tmp on each boot option in PCC boot section) which uses RAM for /tmp. Brasero segfaulted about 1hr 50 mins before the freeze, possibly indicating memory problems as well? How long did it freeze for? Was the drive light on, possibly indicating swapping in progress?

I like to muck around with live distros sometimes that's why my USB key is often plugged in. I had no idea that was bad. I don't know anything about tmpfs, I'm just using the stock settings that came with PCLOS and haven't modified anything. I did install the enlightenment package to test it out and I think brasero might have segfaulted due to some incompatibility with e17, not sure. I checked my memory today with memtest86+ and it said Pass complete, no errors. So I think memory is fine. System froze for few minutes before I did REISUO. I don't remember about the drive light. Thanks for any help.

Starting a while back, I was having what appears to be the same thing happening on my main system which is an AMD Phenom quad core 3.4 Ghz processor and running 4 Gb of memory. This is the 32 bit pclos kde OS that I have been running and updating almost daily for years.

It was happening a couple times a day with other symptoms besides the total hang.

Sorry at the moment I don't remember what they were.

Anyway, I was running the 3.2.18-pclos2.pae.bfs kernel when this started.

After a couple days of this, I thought to boot using the previous kernel which is 2.6.38.8-pclos1.pae.bfs.

I have been running on the 2.6.... kernel for about a week now with no hang.

If you want to try booting with this kernel, I can reboot my system into the 3.2....kernel and see if my problem returns.

By the way, I am running an ASUS M4A89GTD PRO/USB3 motherboard and an AMD Phenom II 965 black processor.

EDIT

Ok, I am back up on the 3.2.18-pclos2.pae.bfs kernel.

I'll report any hangs here if they happen.

I did get an odd boot already. When the kde desktop came up, I got a message to the effect that the Plasma Desktop Shell closed unexpectedly. When I closed that window, the screen went totally black except for a very small quarter inch by half inch window showing on the upper left of the screen. Dragging the corner of it to make it larger, produced a window having to do with "volume" but I don't remember what else it said because I have almost no short term memory and used the last of the memory on my digital camera that I use to document unexpected output on the first message about the Plasma Desktop Shell.

When I closed that window the screen went totally black so I did a Ctrl-alt-bkspace and got the normal log in window from which I was able to log in normally.

I suspect that this was just the result of being the first boot using a different kernel but I really do not know.

EDIT

Well, it has been several days and my machine no longer has the problem no matter which kernel I use.

There have been a batch of updates since I first had the problem so I assume one of them must have fixed it.

Hello. I've found what the problem is. It is Skype 4.0. I installed Skype 4 according to unofficial instructions posted on the forum by a user (basically just extracting the downloaded archives to their resp. folders). It seems that leaving skype on for a while freezes the system. I hope there is an official skype package soon.

you could try using the older kernel suggested previously and see if that helps, the new skype package, i think that is being tested now and should be ready soon
