Hi @kosson,
Your bug seems duplicate of Bug #1910555. Take a look there for workaround till Canonical fix gets released. 😉 Just a obsolete function ioremap_nocache (and one more thing) together with delayed new release of bcmwl-kernel-source (who knows why), where new patch has added, dealing with the changes.
Hope this helps.
