There are a long discussion about the cpufreq VS cpu hotplug dead lock issue in lkml. Do you still see the issue with latest base kernel? please re-open if this happens still with 2.6.18-rc4 or later. I just saw this happen right now with 2.6.18-rc4. I hadn't seen it before, but only just compiled a kernel with hotpluggable CPU support. saw the same on 2.6.18-rc4 on my X60s (1702-55G) now compiled 2.6.18-rc5 and it is gone. acpi-cpufreq and speedstep-centrino now are mutually exclusive (both say 'Device or resource busy' on modprobe when the other is loaded). seems reasonable although I haven't seen this before 2.6.18-rc5; cpufreqd only starts with speedstep-centrino loaded but works properly now. looks like we are okay as of 2.6.18-rc5. thanks for testing. closed. |
