Memory check? After this, dmesg is almost same as in 2.6.19.2. But here is another observation:: migration_cost=18 for 2.6.19.2 migration_cost=87 for 2.6.20-rc5 How does this parameter value impacts the kernel? Lastly, this about Intel RNG: For 2.6.19.2 intel_rng: FWH not detected For 2.6.20-rc5 intel_rng: Firmware space is locked read-only. If you can't or intel_rng: don't want to disable this in firmware setup, and if intel_rng: you are certain that your system has a functional intel_rng: RNG, try using the 'no_fwh_detect' option. Is this a bug? Or, something wrong with my H/W? ~Akula2
