Subject: kernel panic caused by brcmsmac Broadcom driver?

Hello,

Around this one or two weeks, my MacBook Air 2010 installed in Arch
Linux has been caught in kernel panic during data transmission over
wireless connection.

At first, I encountered this issue after upgrading kernel to v5.8, so
I thought the issue was specific to that version. But the issue is
persistent even after downgrading kernel to v5.7.12 and linux-lts
(v5.4.61). I found the similar issue in Arch Forum[0] and this mailing
list[1].

So now, my assumption is this issue comes from other Broadcom driver
updates or my broken hardware.

Here's my kernel panic log and other information with reference to
Kdump ArchWiki[2]. Any suggestions?
