Hi,
a box running Arch on AsRock QC5000-ITXPH has some issues with it's
ethernet chipset since several days:
https://dpaste.org/hVfk
Network is stuck then and it somehow resumes after 1 hour or so.
I stumbled upon https://bugzilla.kernel.org/show_bug.cgi?id=199549, but
changing the powermanagement did not help.
The issue appears with 5.6.x and also 5.4.x LTS, now even the DHCP
request failed after rebooting with 5.6.11.
As it appears with both kernel branches, I hardly believe it's a kernel
issue. But dying ethernet chipsets on a board?
Regards
Bjoern
