Appears to have already been addressed in latest version.
Problem was present in eCos v2.0. When a spurious interrupt occurred,
interrupt_end() was never called and the scheduler was still locked on return
to the application.
In eCosPro v3.0.23, there are changes in the arm vectors.S file that
specifically address making sure the scheduler is unlocked when dealing with
spurious interrupts.
In /hal/arm/arc/current/src/vectors.S
// For a spurious interrupt, pass a NULL object. interrupt_end() will
// handle that and still unlock the scheduler.
Status on this issue should be closed.
