I've rebased my patches to letux-4.8-rc1 but this resulted in kernel tracebacks for me, escalated to panics if booting with HDMI connected. Booting without HDMI connected usually worked, as did modprobe -r omapdrm; connect HDMI; modprobe omapdrm. I merged 4.7-rc2 to see if it would help but it didn't. I've not yet had the time to investigate.
OK, I've done at least a tiny step of bisecting: I've tested unmodified letux-4.8-rc1 with unmodified letux_defconfig. I still get consistent tracebacks.
To allow better debugging and have less log noise I reconfigured the kernel to strip some stuff irrelevant to omap5 and enable e.g. DEBUG_BUGVERBOSE. Curiously, although I still get a traceback, it now doesn't panic but continues to boot with apparently working HDMI output.
Sound is still broken however (aplay -l doesn't even show the twl6040, only hdmi audio as card0).
Kernel log attached below.
