OK I find the problem (and solve-it ;-). In the bios there some (very strange for me) configuration for the wifi card, it seem it's same card to handle wifi and bluetooth. And when I pres Fn+F2 he switch to bluetooth and my laptop crash... So because I don't have any bluetooth device I don't use it. After disabling bluetooth in the bios everything work fine. > > No driver (and of course not working) > > > > NetXtreme BCM5756ME Gigabit Ethernet PCIe > > I don't see `BCM5756' or `5756' anywhere in the manpages or the source > of the kernel in of 8.0-CURRENT either.
