Good idea! =:^) It now appears that your bug simply cascaded on a previously unreported bug in earlier kernels. The 3.8 ls -dl isn't too interesting as they were all dirs not symlinks then, and if they hadn't stuck around after a suspend/resume I'd have definitely noticed and reported the bug back then, but it's still useful to confirm. The 3.8 pre-suspend and post resume ls -dl are identical -- no missing dirs (and no symlinks): /sys/devices/system/cpu/cpu0/cpufreq/ /sys/devices/system/cpu/cpu1/cpufreq/ /sys/devices/system/cpu/cpu2/cpufreq/ /sys/devices/system/cpu/cpu3/cpufreq/ /sys/devices/system/cpu/cpu4/cpufreq/ /sys/devices/system/cpu/cpu5/cpufreq/ The interesting results are the 3.8 cpufreq-info. I'll attach the full output, but here's the interesting bit: 3.8 pre-suspend cpufreq-info excerpts (nicely paired, as are the pre-patch pre-suspend results for 3.9-rc): analyzing CPU 0: CPUs which run at the same hardware frequency: 0 1 CPUs which need to have their frequency coordinated by software: 0 analyzing CPU 1: CPUs which run at the same hardware frequency: 0 1 CPUs which need to have their frequency coordinated by software: 1 analyzing CPU 2: CPUs which run at the same hardware frequency: 2 3 CPUs which need to have their frequency coordinated by software: 2 analyzing CPU 3: CPUs which run at the same hardware frequency: 2 3 CPUs which need to have their frequency coordinated by software: 3 analyzing CPU 4: CPUs which run at the same hardware frequency: 4 5 CPUs which need to have their frequency coordinated by software: 4 analyzing CPU 5: CPUs which run at the same hardware frequency: 4 5 CPUs which need to have their frequency coordinated by software: 5 3.8 post-resume (screwed up pairing, so that bit's not a 3.9 thing, I just noticed it in 3.9 due to the now missing symlinks/dirs): analyzing CPU 0: CPUs which run at the same hardware frequency: 0 1 CPUs which need to have their frequency coordinated by software: 0 analyzing CPU 1: CPUs which run at the same hardware frequency: 0 1 CPUs which need to have their frequency coordinated by software: 1 analyzing CPU 2: CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 analyzing CPU 3: CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 analyzing CPU 4: CPUs which run at the same hardware frequency: 2 4 CPUs which need to have their frequency coordinated by software: 4 analyzing CPU 5: CPUs which run at the same hardware frequency: 3 5 CPUs which need to have their frequency coordinated by software: 5 -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
