I see a patch in 4.0 that might be related. Can you please test gentoo-sources-4.0.5 and let me know the result? Hi, with 4.0.5 no lucky, the same error u.u Thx. From what I read these are just warnings. Are you experiencing any problems from this? Is something related to i915 not working? Hello messages are sent as "ERROR", then I guess it only need to be pass them as warnings. in other distros are patches for that. The kernel works fine with i915, but maybe only for curiosity, i have an "00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)" it use i915 driver (via lspci), but if a disable the i965 on the kernel or in the make.conf the driver don't works. can be related, i really don't know. is this still a problem with more recent kernel ? please open a new bug if the problem persist with a more recent kernel. |
