Hi James In linux 3,2 and 3.3 nouveau was using a custom i2c-algo-bit functions, which are possibly causing the issue in your case Since linux 3.4 we have reverted to using the in-kernel functions Author: Ben Skeggs <bskeggs@redhat.com> 2012-05-04 05:38:49 Branches: remotes/linus-stable/linux-3.4.y, remotes/linus-stable/linux-3.5.y, remotes/linus-stable/linux-3.6.y, remotes/linus-stable/master, remotes/linus/master drm/nouveau/i2c: resume use of i2c-algo-bit, rather than custom stack Previous issues with i2c-algo-bit have now been resolved. This is a revert of f553b79c03f0dbd52f6f03abe8233a2bef8cbd0d mostly, due to fixes in the i2c core repairing the original issue, this code isn't required and was causing regressions.
