This is very strange, apparently the same interrupt has been assigned
to both the PMU (performance monitor) and to the axon device driver, which
should really not be possible. The interrupt management complains
that they cannot live on a shared line.

No idea what could have changed here, I'll wait to see what the older
kernel shows.
