Ok, with this (omitting the kgem commit), I get this backtrace (similar to my
original reported trace):

Backtrace:
0: /usr/lib/xorg/modules/drivers/intel_drv.so
(__kgem_retire_requests_upto+0x71) [0x7f3876671f91]
1: /usr/lib/xorg/modules/drivers/intel_drv.so
(sna_put_zpixmap_blt.isra.128+0x1b2) [0x7f38766c03e2]
2: /usr/lib/xorg/modules/drivers/intel_drv.so (sna_put_image+0x2f8)
[0x7f38766c0f18]

Perhaps this is expected, since that commit can fix this (?), now commenting
our the assert in question but including the commit otherwise...
