Thanks for the report.
the dmesg output are only diagnostics, they should be removed but do
not indicate any error.

your configuration command is incorrect though, "queue 90Kbit/s"
as queue size can be expressed only in slots or in bytes. The parser
is sloppy and ignores everything after the 'K' so it understand
it as 90Kbytes, but you should not count on that

cheers
