From: Julio Faracco <jcfaracco at gmail.com> Driver virtio_net is not handling error events for TX provided by dev_watchdog. This event is reached when transmission queue is having problems to transmit packets. To enable it, driver should have .ndo_tx_timeout implemented. This serie has two commits: In the past, we implemented a function to recover driver state when this kind of event happens, but the structure was t...

...ion. Googling, I see there is some history of e100e driver having issues, and I'm wondering if it could be related. Does anyone have any thoughts on where to do with it, as I'm assuming it will hang again later.
