It is no longer working on one of our older machines, a Z97 chipset, with a Qualcomm Atheros E220x NIC.
This uses the alx driver

Hi,

what isn't working on the 6.2 kernel?
Does it show up in the kernel log (dmesg), in lspci, ip link, ..?
Are there any error messages in the journal?

Please provide some more information, otherwise it's pretty hard to say what went wrong.
Also, post the output of pveversion -v, that is always helpful.
 
I couldn't get any information off of the host at the time because it had no network connection.
I got a USB NIC and rebooted back into 6.2.16 / 8.0.3 and neither NIC worked.
After a grub-install and update and another reboot both NICs started working.
Suggest something was munged in my initrd but I'm not sure how that happened and how it was bad enough NICs didn't work but it still booted.
C'est la vie.
