Same with intel if the acpi_idle driver is used. If the intel_idle driver is used you see power_start events, but double power_end events. git commit f77cfe4ea21760268c0277fa3e4b02dfd2a2c2f4 fixes that issue, but needs some other patches on top: 20c457b8587bee4644d998331d9e13be82e05b4c 25e41933b58777f2d020c3b0186b430ea004ec28 (61a0d49c33c7fd57c14895e5b0760bd02b65ac1f) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
