I've had the same sort of problems on 2 different BayTrail tablets (a Onda
v975w and a WinBook TW100), usually hanging hard during package installation
and was wondering whether you would resubmit your patches to be merged (I
understand that the CPU detection was problematic), or whether I should ship
those in our vendor kernel in the meanwhile.

I'll report shortly how well that patch series works after testing.

Those 2 patchsets got merged upstream now, correct?

Cheers
