I have not (yet) tried "processor.max_cstate=1" as described in Bug #669535, but with "nolapic_timer clocksource=jiffies" kernel parameters everything seems to work. (~24h up and running with no trouble)
There is also 1.15c bios update for AMILO Pi 2540, that I have not tried yet.
My system is Ubuntu 13.04 with Linux 3.8.0-23-generic kernel
I have AMILO Pi 2540 laptop
With Intel T2398 (http:// ark.intel. com/products/ 35153/Intel- Pentium- Processor- T2390-1M- Cache-1_ 86-GHz- 533-MHz- FSB), my system worked perfectly.
After upgrading to Intel T8100 (http:// ark.intel. com/products/ 33916/Intel- Core2-Duo- Processor- T8100-3M- Cache-2_ 10-GHz- 800-MHz- FSB), I started to having problems as described in this (and #669535) bug.
