When running xrandr --listproviders, both nouveau and Intel are listed. However, after using xrandr --setprovideroffloadsink nouveau Intel, running DRI_PRIME=1 glxinfo | fgrep "OpenGL vendor" still shows Intel.
dmesg includes the following line:
[ 21.537016] nouveau E[ PGR][0000:01:00.0] grctx template channel unload timeout
Attached are Xorg.0.log, dmesg, and an mmiotrace of glxinfo running through bumblebee.

The issue here is with the bringup... the driver doesn't load, which means X doesn't see it, etc.
[ 15.063868] nouveau E[ PBUS][0000:01:00.0] MMIO write of 0x00000004 FAULT at 0x620018 [ IBUS ]
[ 15.149993] nouveau E[ PBUS][0000:01:00.0] MMIO read of 0x00000000 FAULT at 0x500c30 [ IBUS ]
Not sure if those are (semi-)expected.
mmiotrace sent to firstname.lastname@example.org
Please try (a) 4.3-rc6 kernel, (b) 4.3-rc6 kernel booted with nouveau.config=War00C800_0=1 and see if either of those help. If the latter helps, please include your 'lspci -vnn -d 10de:' output.

Option b) worked. Attached is the lspci output.
