MacchiatoBin networking breaks on upgrade

Postby krovetz » Thu Jun 30, 2022 12:31 am

Hello,

I recently was reinstalling Alarm on MacchiatoBin and the directions at

https://archlinuxarm.org/platforms/armv ... cchiatobin

worked correctly. However, after pacman -Syu, networking no longer works. Looking at the boot log, it looks like it doesn't find the ethernet driver after upgrade.

BEFORE:
$this->bbcode_second_pass_code('', '[ 7.322583] mvpp2 f4000000.ethernet eth2: PHY [f212a200.mdio-mii:00] driver [Marvell 88E1510] (irq=POLL)')

AFTER:
$this->bbcode_second_pass_code('', '[ 7.948128] mvpp2 f4000000.ethernet eth2: PHY [f212a200.mdio-mii:00] driver [Generic PHY] (irq=POLL)')

These issues are usually due to an upgrade of the kernel, the bootloader (uboot), or the firmware package. By downgrading those one at a time, you should be able to isolate the problem.

I also just tried reinstalling Alarm on an Odroid-C1. Following the instructions gave me a working system, but as soon as I pacman -Syu, the system no longer worked. I don't have serial access to the C1, so I can't look at the boot logs on the failed system.

These are old systems, so I don't expect any work to be done fixing them, but I will try again in a couple of months in case the problem happens to get resolved.

If you can mount the storage device with the updated (and broken) install on a different ARM machine, you will be able to chroot into it and perform the package-by-package downgrade I suggested. After identifying the offending package - likely to be among the three I listed - you can then withhold that single package from upgrading, and have an "almost up-to-date" system.
