Mouse & keyboard freezing

Recommended Posts

hello,

well i have spring 2007.1 installed and am generally impressed. I have one problem that is very aggravating. My mouse and keyboard will freeze at random times and I will have to do a power restart. This problem goes back to 2007.0 edition. It can sometimes be 15 mins after I boot or 4hrs. The only thing i notice is that the majority of the time I have MCC and software updates running or have run earlier in session. It may be my imagination but this problem seems to have started when i upgraded the original rpmdrake from 2007.0 I have looked in syslog & messages but nothing seems abnormal. I thought maybe it was a problem w/the X server and was hoping that the upgrade is a to Spring would solve this trouble. But no luck. I've run a memory test and that came out ok. The fact that it can happen 10mins or 4hrs into a session would seem to rule out heat. I have this laptop dual booting w/XP and that does not experience any problem. Any suggestions on where to look would be most helpful. I would like to stick w/Mandriva if I can get this problem solved. Here is a readout of dmesg;

Actually I had the very same symptom (system freezing irregularly) on this machine. After a lot of searching I found it was CPU related. This is a dual boot system too, but I had BSODs pointing in that direction with Win$ rarely. Syslogs were normal the same way. Some hints came from attempts to boot newer kernels, with error messages (kernel panic) directing me to the CPU.

 

A temporary workaround was to decrease CPU speed using BIOS settings (yet the processor wasn't overheated or overclocked before). I could only assume the processor was getting too old to run at the highest freqs (2.5 years)?!?

 

I'm absolutely unsure wether your case has the same origin, but you may give it a try. I would be interested in the results. A good sign of indicating a total system freeze in X windows mode was a system monitor running in the panel. Thus I could rule out input device problems.

I'm sorry what do you mean by that. All I have is Ksysguard running monitoring the cpu temp. it moderates between 54-65 C. At least I assume its giving me temp in centigrade. Also i've never noticed an option on throttling down cpu in bios. where did u find it and what did you set yours to.thanx...

Sorry if that was not so clear. With "system monitor" I meant a CPU/system performance tool, not a heat measuring tool. With gnome, you can put a small representation of gnome-system-monitor into the panel. I'm sure something similar does exist for KDE, too. The small app shows how much load the system is actually taking; the output is updated every second or so. When the system monitor output freezed, I knew it was time to reboot (no keyboard or mouse input possible, too).

 

So what I did was the following: After rebooting I opened the BIOS menu and set the FSB multiplicator lower than normally used for this CPU. With a 200Mhz front side bus and a multiplicator of 11, you could tell your system to run at 200Mhz x 11 = 2200 Mhz. The BIOS on this machine allows to set the multiplicator by 0.5 steps. After lowering the factor by 1.5, I could go back to normal operation with no freezing. In the example above, you would get 9.5 x 200Mhz = 1900 Mhz. This is no optimum, but until total breakdown occurs, I can go on working.

 

BIOS settings and options tend to vary at quite an amount between different boards/manufacturers, so you may or may not have this possibility. Older mainboards offered setting FSB multiplicators by manually setting jumpers on the board, newer ones may have this option accessible through BIOS menu. Mine is in the Miscellaneous section.

 

If you have the same possibility to slow down your system, you can try degrading the actual value (probably default now) by minimal steps, then save settings, reboot and observe any possible improvement. But as mentioned before, this is not a cure for any possible error causing the strange behaviour, just a workaround. And it's not guaranteed to help in your situation. Before trying that, I'd make sure you have a "hard" system lockup (indicated by system monitor and no reset sequence or MagicSysRq key sequence possible). I'd try CTRL-ALT-Backspace, CTRL-ALT-Delete, ALT-PrtScreen-b, in that sequence (i.e. try the latter only if the former fails).
