Hi everyone, I am running FreeBSD 11.0-RELEASE-p2 #0 on an old toshiba laptop. I have had drm.i915.enable_rc6=7 on /boot/loader.conf for a long time (at least in 10-RELEASE) and I thought it was working. I have only realised now the following error in dmesg: drmn0: taking over the fictitious range 0xc0000000-0xd0000000 error: [drm:pid813:__wait_seqno] *ERROR* WARN ON: !ring->irq_get(ring)error: [drm:pid813:ironlake_enable_rc6] *ERROR* failed to enable ironlake power power savings I don't know if it is a regression in FreeBSD 11 or if I just never noticed the error before. Is there anything I can do to enable powersaving? Thanks, Fernando
