Hi again! I tried to boot into VGA mode with NMI watchdog=2. System loads OK, nmi counter is increasing on both CPUs (procesor is HT), but when I start to load the CPU (compiling kernel), system locks without any message. Even blinking cursor disapears. I will try to do netconsole loging, but I can't promise any results for today.
