jhb 2010-06-23 17:51:11 UTC FreeBSD src repository Modified files: (Branch: RELENG_8_1) sys/dev/acpica acpi_cpu.c Log: SVN rev 209473 on 2010-06-23 17:51:11Z by jhb MFC 209213: When updating individual CPU's lowest Cx state to use, never set it to a state lower than the lowest one supported by the current CPU. This closes some races with changes to the hw.acpi.cpu_cx_lowest sysctl while Cx states for individual CPUs were changing (e.g. unplugging the AC adapter of a laptop) that could result in panics. Approved by: re (kib) Revision Changes Path 1.79.2.7.2.2 +3 -1 src/sys/dev/acpica/acpi_cpu.c
