[GTALUG] Intel Bay Trail bug fixed in 5.3!

[D. Hugh Redelmeier]

Bay Trail is a family of processors/SoCs introduced in 2013.  They were 
ubiquitous.  And they suffered hangs under Linux.

The work-around has been to turn off some power-saving capabilities, 
crippling the usefulness of these "low-power" chips.  (I suspect most 
users never found the magic incantation to do this and so have just given 
up on running Linux on these systems.)

I'm subscribed to the bugzilla entries.  I just got a notification of
the thousandth comment added to one.  A kernel patch has been
submitted by Intel and accepted for 5.3 (months away).  The whole
useful life of this SoC has been impaired.

This patch is work-around code for a chip bug.  The patch itself is
restricted to "Valleyview" which is a name for something that covers
all Bay Trail chips, and only Bay Trail chips.

Actually the Intel open-source devs have been working on fixing this and a
patch-series which should improve things wrt this has been queued for merging
into 5.3 (it just missed the 5.2 merge window), see:
