Description Hans de Goede 2015-08-27 09:46:49 UTC
Hi,

There is a problem with nv46 based cards hanging while waiting for vsync, due to MSI interrupts not working reliable with these cards.

There was some discussion upstream on how to best fix this, this has been fixed now by a patch which disables MSI interrupts on these cards:

http://cgit.freedesktop.org/~darktama/nouveau/commit/?id=cdb40514ebc062a72c7451aeecb6066d0dd4a9a8

This patch has been queued for merging into 4.3, but since this bug makes these cards practically unusable and the patch is quite simple I would like to ask you to include the patch in Fedora kernel builds until it trickles downstream.

Thanks & Regards,

Hans

Added on all branches.  I had to munge the path in the patch because the nouveau tree uses that weird directory layout, but otherwise it's identical.
