Subject: [crash] kernel BUG at drivers/cpufreq/cpufreq.c:1060!


2.6.24-rc4-git5, got this cpufreq crash on x86 64-bit, during 'make 
randconfig' random bootup testing:

powernow-k8: BIOS error - no PSB or ACPI _PSS objects

kernel is 2.6.24-rc4-git5-ish + x86.git. (but no cpufreq changes to the 
upstream code) crashlog and config attached. Will try with vanilla 
-latest as well.
