he CCP has the ability to perform several operations
simultaneously, but only one interrupt. The current design
exposes a window when using MSI/MSI-X interrupts wherein
state can change but no interrupt is generated; this can
lead to a hang in the engine. Switch to a tasklet backend
which allows serializing state changes, handles processing
of the interrupts, and avoids the loss of task completion
status.
