SubjectHard lockups under high CPU load with DynTicks - RCU Related?
Hi

I've raised https://bugzilla.kernel.org/show_bug.cgi?id=84131 and
attempted to bisect

The bug I'm stumbling on happens on both and Intel Sandybridge and AMD
Kabini system - it manifests itself as a hard lockup when the system
is under high load

If I switch off DynTicks the problem doesn't happen - I bisected by
compiling Chromium marking each one good or bad if the system starts
to lockup

I'm not sure if I've filed the bug under the right Product / Component

Please let me know if you'd like any more diagnostics

Cheers

Mike
