Re: increased power consumption lately?

I found another solution. Modifying the DSDT file by removing

        Method (_L06, 0, NotSerialized)  // _Lxx: Level-Triggered GPE
        {
            If (LAnd (\_SB.PCI0.IGPU.GSSE, LNot (GSMI)))
            {
                \_SB.PCI0.IGPU.GSCI ()
            }
            Else
            {
                Store (0x00, \_SB.PCI0.IGPU.GEFC)
                Store (0x01, SCIS) /* \SCIS */
                Store (0x00, \_SB.PCI0.IGPU.GSSE)
                Store (0x00, \_SB.PCI0.IGPU.SCIE)
            }
        }

seem to solve the problem, as discussed here
https://bugs.freedesktop.org/show_bug.cgi?id=98501

I will keep an eye on that bug report and see what happens.
I should also mention that I am running the Linux i915kms driver
https://github.com/FreeBSDDesktop/freebsd-base-graphics

Since we're constantly merging updates from Linux maybe there will be a fix
for this soon.
