Re: [gentoo-user] wlan0 failed to start

[Tomáš Hájek]

dmesg says only:

tom@tombook ~ $ dmesg | grep -i firmware
[    0.099927] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored

I already have linux-firmware in my system, just put brcmsmac in my kernel
(was set to =n), and still have same result tough.
Only difference is that rfkill list all now see wifi card and says that it
is not blocked (before it could not see a thing)

Any other ideas?
Thanks
TomH
