Hey guys,
after upgrading to 4608f064532c ("Merge
git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next")
my kernel log gets constantly flooded with the below message and wireless stops
working ... just in case you haven't had a report on this yet. Downgrading back
to older v4.16-rcX kernel gets everything back to normal working state; haven't
had time for bisection yet, but hopefully the below would provide some clue.
