I use lilo, and I checked that I changed the two/four digits correctly in /etc/lilo.conf. By chance I left the boot sit there for more than the typical minute, and got multiple messages like INFO: rcu_sched self-detected stall on CPU { 3} (t=60000 jiffies g=-256 c=-257 q=193) rcu_sched kthread starved for 50027 jiffies! right after the above "Booting the kernel." line. Do I need to activate a different kind of clocking or a CPU feature in 4.1.x? Peter.
