Someone else complained too. I am currently travelling, but I am currently trying to reproduce. I will report back when I have something useful to share. In the meantime - you can try this firmware: https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/log/?h=Core6 Of course, even if this one does work, we'll still make sure that your current firmware will work with the current driver.
