Hi All,
There is a bug in the bleeding-edge branch. Using the ondemand governor
and acpi_cpufreq scaling driver the system hangs while trying to reboot or
trying to offline a cpu manually. The last call where I have tracing turned
on is __cpufreq_governor(data, CPUFREQ_GOV_STOP);
[ 38.138236] __cpufreq_remove_dev: cpufreq: __cpufreq_remove_dev:
unregistering CPU 1
[ 38.146663] __cpufreq_governor: cpufreq: __cpufreq_governor for CPU 0, event 2
[ 71.562262] ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
It looks like the breakage comes from the removal of the sysfs files in the
incorrect order. While rebasing my patches onto bleeding edge I found this
problem as well. I have a couple of hack patches that workaround the issue
when using my driver if anyone would like to see them.
