Grumble. So, how will this be fixed? Sprinkle the code with
preempt_disable()/enable() pairs? Advise all users (well, me) to disable
preemption? Change the code so it no longer acts on intermittent EDID failures?
Ask your colleagues to design sane hardware that doesn't rely on software
interaction for timing-critical operations ;) ?
FWIW, I'm perfectly happy to disable preemption in my kernel, haven't run a
distro-provided kernel since 2.6.27. But your explanation sounds like this
could bite a lot more users than just me.
