Subject: linux-4.5-rc1 TI pandboard-es wifi wlcore locks and reset
Date: Mon, 25 Jan 2016 23:47:56 +1100 [thread overview]
Message-ID: <CANfgCY2nHh+vZ=JOimJdKKKs2JgM-c7m+3ePZtS3XhqyXNkDUQ@mail.gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 399 bytes --]
Just tried the new kernel release on faithful pandaboard es with the
new 4.5-rc1 release.
There is a problem with the wifi modules once the modules are loaded.
Looks like the wifi firmware gets loaded put no response after that
causing recovery action.
the kernel 4.4 works quite happily with this board.
Here is a dmesg dump in the attachment.
Anyone have any ideas here?
Regards,
Ross Green
