Something is not quite right here. I built rc2-mm3 and booted (uni processor, amd64, preempt on). mm3 lasted about 30 mins before locking up with a dead keyboard. I had mm2 reboot a few times over the last couple of days too. 11-mm3 uptime of 2 weeks+ 12-rc2-mm2 reboots once every couple of days 12-rc2-mm3 locked up within 30 mins using X using kmail/bogofilter My serial console does not seem to want to work. Has anything changed with this support? TIA, Ed Tomlinson
