OK, I rolled my own patch, 2.6.13-rc4-ck1-reiser4+this patch and it appears to be running on my desktop Asus A7N8X very well: I am running with Local APIC/IO-APIC/APIC Timer and forceapic. Time does not appear to be running slow, and I do not appear to have a slow boot. sbh@rocket ~ $ cat /sys/devices/system/timer/timer0/dyn_tick_state suitable: 1 enabled: 1 using APIC: 1 [4294683.959000] dyn-tick: Maximum ticks to skip limited to 803 [4294683.959000] dyn-tick: Timer using dynamic tick The nvidia driver also works, and the most unexpected thing is after a few hours of running it seems stable :) So, to repeat I'm only reporting sucess, I'm unsure of the power savings but this computer is on all day.
