Multiple KDE application crashes (signal 11, SIGSEV) in MEPIS and Kubuntu
(This may belong under Hardware, but I won't assume.)
I'm getting repeated application crashes for (it seems) just about everything I run in KDE, on MEPIS 7.0: "[This application] caused the signal 11 (SIGSEV)." It has happened for kmix, korgac, ksmserver, kicker, artsd, kpackage, kiouiserver, klipper, kded, knotify, adept, and guidance-power-manager.py.
In the desperate hope that I could get a desktop that functioned for more than a few minutes, I installed Kubuntu 8.04 (Hardy). (I am now triple-booting MEPIS, Kubuntu, and Windows XP.) But the crashes are there, too. This makes me think it's related to the hardware.
I recently had new processor, graphics card, motherboard, RAM, and power supply installed. For some reason (I think because MEPIS wouldn't recognize my ethernet port), I re-installed MEPIS, found the kernel/driver patch (see here), and got it working -- sort of. Soon, apps started failing; even X re-started (and still does).
Nothing seems to be crashing at the terminal login (tty0), though I don't run a lot of apps there. But running command-line apps (like apt-get) through Konsole does (or can) cause a crash.
The output of lspci (from MEPIS, not Kubuntu) is:
Well, I think you need to check your RAM first. I had a problem not long time ago, when my RAM was detected correctly during system startup, but when I booted an OS, they kept crashing. Than I checked my RAM with Memtest, and it showed, that there were many read-write errors. I replaced the bad RAM module, and everything is fine since then.
The conclusion is: your RAM can be bad, even when the basic system check (by BIOS) during startup says that its good.
