Description marcusvini 2008-05-30 00:26:18 UTC
When installing the ebuild in portage, dmesg shows this message:

NVRM: bad caching on address 0xffff81011c820000: actual 0x173 != expected 0x17b
NVRM: please see the README section on Cache Aliasing for more information

On nvnews website it is being said that there is nothing to worry about it, but to fix it they propose the patch I attached this bug report, also I proposed an ebuild bump to 107.08-r1, where the file is patched with the instructions present on the post where is explained the cause of this and the patch needed to fix it:

The patch to fix nv.c
Comment 3 Tony Vroon (RETIRED) gentoo-dev 2008-05-30 09:05:32 UTC
This is not a patch approved by upstream (i.e. posted by zander or AaronP on nvnews in a sticky topic). I'm sorry to report that I am not willing to carry such patches in an ebuild, especially when they serve no purpose but to squelch a harmless warning.
