Describe the issue you are experiencing

Upon upgrading from 18.2 to 18.3, my system briefly became visible, but then dropped off the network. I connected directly to the console to diagnose, and found messages about can't disable ASPM; OS doesn't have ASPM control, along with repeated netdev watchdog: cpu: 2: transmit queue 0 timed out rtl_rxtx_empty_cond == 0 (loop: 42, delay: 100)

It looks like ASPM is repeatedly failing on the rtl8169. I added pcie_aspm=off pcie_port_pm=off to the boot command line, with no success. Eventually I had to switch back to 18.2 on boot slot B to recover.

What operating system image do you use?

generic-x86-64 (Generic UEFI capable x86-64 systems)

What version of Home Assistant Operating System is installed?

18.3

Did the problem occur after upgrading the Operating System?

Yes

Hardware details

KAMRUI Essenx E1 Desktop Mini PC with N150 processor

Steps to reproduce the issue
