Kernel stability on baytrail machines

Hello everyone,
aprox. 6 months ago I started facing random freezes on my baytrail based
computers I manage. It took me a while before I found a bug report in
freedesktop bugzilla named "complete freeze after: drm/i915/vlv: WA for
Turbo and RC6 to work together" -
https://bugs.freedesktop.org/show_bug.cgi?id=88012. It took a few more
months for this bug to escalate into MAJOR importance and was later
moved into kernel bugzilla as "intel_idle.max_cstate=1 required on
baytrail to prevent crashes" -
https://bugzilla.kernel.org/show_bug.cgi?id=109051.
Based on the ammount of comments in both bugtickets and probably
connected observations on different linux distros forums, this seems to
be a showstopper on mainstream Baytrail based machines for many users.
I'm trying to understand, how visible (and thus important) is this
instability across baytrail machines on linux kernel across population.
I do feel that the importance of the mentioned bug is currently
underestimated. Can anyone here give a note, how much current linux
kernel is supposed to be stable on general baytrail machines?
Cheers,
