I'm not able to capture any output :/ keyboard does not work , netconsole does not have any output when freeze occurs, nor I have any 'BUG:' , 'Oops:' or the like messages in any logs. The only thing I noticed is : ... Clocksource tsc unstable (delta = 4686944957 ns) ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^ <-- may be some sort data corruption :/ ... as latest kernel message before most freeze. Booting with different clocksource does not make any difference. I do not use nvidia , in fact I don't use any external kernel module on that box. Anyway it seems to work fine on non-SMP also my laptops does not have that problem with the same kernel. If needed I can post the config but I tested a lot different configs with the same result. Is there any rt-git tree I can test ? Regards, Gabriel [1] http://194.231.229.228/lara/lara.html http://194.231.229.228/lara/lara.lspci
