--- Comment #111 from John <jbmacbrodie at yahoo.com> ---
The notes for 4.2.6 claim to fix one problem that causes GPU locks.  When I
added the incremental patch set, the longest it ran was about an hour (usually
it froze within 5 minutes.)  I had just stopped a 6 day run (24/7) on my (ASUS
baytrail) T100 specific 4.2.5 kernel (no args, 50% GPU cap) (with sdhci
patches)  The freezes in 4.2.6 now seem to be independent of GPU frequency for
my setup.
