<pre>i915.enable_rc6 was a debug and development option, never meant for normal use.
In most cases where it presumably helped, its effects were so widespread that
it was near impossible to pinpoint what the actual functional impact was that
helped.
The enable_rc6 option is not coming back.
So please let's rather focus on the bug you experience, i.e. screen going black
and losing sync.
Please add drm.debug=14 module parameter, and likely something like
log_buf_len=4M or similar. Attach full dmesg from boot to the bug. Please also
reproduce the problem, and attach the dmesg after that. (I suspect we need the
two; I don't think it's likely the latter will include the info logged at boot
anymore with all the debugging enabled.)</pre>
