Well, what I would do in this case is to first do "lspci -v" and compare my
hardware specs and
driver in use with that reported in the BZ to see how they match up. It is not
inconceivable that
an error message may be the same while the underlying issue different than reported in a
BZ.
Not a driver match. Bug report is Broadcom, mine is Intel (iwlwifi)
