Support for cores revisions 0x17 and 0x18 disabled by module param allhwsupport=0. Try b43.allhwsupport=1

  • 772

I'm using Ubuntu 14.04.2 LTS and the boot getting the following warning:

Support for cores revisions 0x17 and 0x18 disabled by module param allhwsupport=0. Try b43.allhwsupport=1

Using the following command at terminal

$ dmesg | grep b43

getting the following output:

[   36.226712] Support for cores revisions 0x17 and 0x18 disabled by module param allhwsupport=0. Try b43.allhwsupport=1
[   36.226716] b43: probe of bcma0:0 failed with error -524

I'd highly appreciate if you help me to figure out this problem. Thanks in advance for your help.

Found this this solution for linux but don't know how to use this approach in Ubuntu 14.04.2 LTS. 

$ lspci -knn | grep Net -A2
12:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)
    Subsystem: Dell Inspiron M5010 / XPS 8300 [1028:0010]
    Kernel driver in use: bcma-pci-bridge


$ dpkg -l | grep linux-firmware-nonfree
14.04

    I suggest installing Broadcom wl driver for this chip.

    Run in terminal

    sudo apt-get install bcmwl-kernel-source

    If you choose to keep b43, you can edit that file in /etc/modprobe.d/ in Ubuntu too.

    But wl should be more stable.

    But if everything works there is no need to worry
