Subject: Re: 4.9.28: VIA velocity hang: how to find cause?

Hello,

This issue occurs on VIA Epia M910E.
Both interfaces suffer from this.
Setting msglvl with ethtool has no effect on the info the driver
provides on any issues.
So how to proceed from here?
If this is a software issue, which I cannot determine, the driver is
useless in its present state.

Kind regards,
Udo
