I'll explain: I'm running here KDE 2.2.1 with server Konsole sessions running, and using mondo-archive program to backup my machine. After the backup finishes part of the backup - the VM panic randomly - sometimes it's the bzip2 process which the mondo uses, sometimes the afio which the mondo uses, sometimes its just the kswapd daemon, sometimes wineX which I'm testing - so as you can see from the pattern - it's not a program or a module that does it yet it happends to me on both machines I have checked the RAM of the machines twice - with memtest86 2.8 for 24 hours - no errors. I checked the machines - one AMD 800Mhz thunderbird + Asus A7V board, and once Pentium 4 1.5Ghz with Intel board (i845 chipset) - so it's not the processors or the boards. I checked the hard drive (40GB EIDE IBM 7200RPM with a fan) - no sectors or any disk problems. Sound card is SBLive - no problems there either...

Thanks, Hetz PS: It seems that there is still some problem with the vger server - I get the first email to subscribe but when I reply with the auth - it doesn't give me anything and I think my ISP doesn't have any issues with ECN. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
