Dear Launchpad Team,
I want to a report errors for my hardware but I don't know if it bug or
problem with the kernel itself. I installed Xubuntu 20.04.1 and I
noticed when it is startup (booting) that are two information (errors?)
shown of the screen. I thinked that this is only a problem with Xubuntu
system but on Ubuntu 20.04.1 I had also this same informations when I
run dmesg command in terminal. I installed also Ubuntu 18.04.5 but in
this system I have also these errors? I think that on Ubuntu 18.04.5 I
have more errors that on Ubuntu 20.04.1.
This is from dmesg on Ubuntu 18.04.5 system:
[ 25.402xxx] brcmsmac bcma0:1: brcms_ops_bss_info_changed: qos enabled: false
(implement)
[ 25.402xxx] brcmsmac bcma0:1: brcms_ops_config: change power-save mode:
false (implement)
[ 26.711xxx] brcmsmac bcma0:1: brcmsmac: brcms_ops_bss_info_changed:
associated
[ 26.711xxx] brcmsmac bcma0:1: brcms_ops_bss_info_changed: qos enabled: true
(implement)
[ 13.771xxx] b43: probe of bcma0:1 failed with error -524
I erased some data with "x" because I don't know if it safe to write
these kind of information public. I am beginner.
One of the Launchpad user told me that this is not error. Okay but I
have problem with my Wi-fi. This don't work sometimes. I found the fix.
I musted to change in panel configuration of my router channels for 2.4
Ghz. It had auto option enabled. I musted limited to 3 channel because
when this was high value my wi-fi doesn't work. I think that this is
problem with brcmsmac driver because on bcmwl-kernel-source I don't
have this problem on bionic (Ubuntu 18.04.5).
I have this same problem on Ubuntu 20.04 and 20.04.1. I had also
problems with bcmwl-kernel-source on Ubuntu 20.04.1 after some update
but maybe this is fixed now. I don't know because I switched back to
bionic.
Some terminal output:
uname -a
5.4.0-65-generic #73~18.04.1-Ubuntu SMP Tue Jan 19 09:02:24 UTC 2021

On lsusb output
I can see Broadcom Corp. BCM2070 Bluetooth 2.1 + EDR. So this is a
bluetooth card. I don't know if it the same device. I think that
bluetooth and wi-fi is supported by this same device but like you can
see there are different names.
On lspci -nnk output
BCM4313 802.11bgn Wireless Network Adapter
Kernel driver in use: bcma-pci-bridge
Kernel modules: bcma
Can you fix it? Broadcom users have a lot of problems on Ubuntu system.
Maybe if you fix brcmsmac driver this will be not problem anymore. Sorry
if this doubled bug, maybe someone in the past report this.
