Public bug reported:
Issue:
Between upstream kernel v3.19 to v4.2,when Intel SMEP/SMAP protection was
triggered by some wild function call or data access, the screen would be
frozen and never come back,but the system does not hang.
Generally, an SMEP/SMAP violation should cause the involved process
killed, an oops from page fault exception generated to the syslog, and
the system survived.
Fix:
One patch from 4.3 kernel fix this issue
