Bug#993091: linux: kernel oops on Olimex A20-OLinuXino-LIME2, Allwinner sun7i (A20)
Source: linux
Version: 5.10.46-4
Severity: normal
X-Debbugs-Cc: andi@debian.org
Dear Maintainer, hi all,
after upgrading a A20-OLinuXino-LIME2 board to bullseye, I had problems with the
network interface which could be solved by preparing a tweaked u-boot (c.f. [1]).
However, a few hours later, a kernel oops happended and the board could not be
reached from the LAN again:

I downgraded to the buster kernel for now which was working reliably for months
without issues on the same board.
Many thanks and best regards,
