Three times today. And always during webbrowsing ... What's so special about it? Could it be because it accesses network and disk at the same time? The system has been pretty busy compiling the last days because I did setup a new Gentoo system in chroot environment. No problem whatsoever. I did run 2 x mprime for a day and also no problem. Is there anything I can test? Disable irq balancing? Disabling preemption did not help. Disabling IO-APIC? What can I do to help isolate the problem because it really is annoying and I don't like pushing the reset button. Because if the system locks up *really* nothing works. The screen is frozen, no mouse, no keyboard, no sys-rq, no network ... nothing. Thanks for your help and best regards, Jochen
