#1349350 — 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,

-- 
Michael
