Does your configuration have POSIX_TIMERS enabled? If not, then CPTS
is now also disabled. There are two issues here that we need to solve:
a) find out why POSIX_TIMERS got disabled, and make sure it's always
turned on for normal users
b) find out what's wrong with the driver when CPTS is disabled. This would
be an existing problem that you just never saw because CPTS was
always enabled so far.
