Network connections unstable after running network apps (haikudepot, webpositive).

[howard.a.johnson]

I'm using the latest nightly build. Brand new install, but the issue has happened with previous installs. Ethernet pings work fine, but as soon as I use WebPostive or HaikuDepot, the ping response time goes from like 10ms to thousands. The whole thing chokes. Network connection drops, comes back, drops, comes back, drops...etc. Looked in syslog and found a bunch of errors (I'd post the logs, but right now the box is network isolated). Goes like this:

KERN: [atheros813x] (alc) DMA write error! -- resetting

KERN: /dev/net/atheros813x/0: media change, media 0x22 quality 100 speed 0

KERN: /dev/net/atheros813x/0: media change, media 0x900130 quality 1000 speed 1000000000

over and over again.....

The box is HP Envy 700-147c. (​https://support.hp.com/us-en/document/c03933886)

Network card (per HP website above): Technology: Atheros AR8161L gigabit Ethernet controller Data transfer speeds: up to 10/100/1000 Mb/s Transmission standards: 1000BASE-T Ethernet

There are some changes in upstream FreeBSD which might be relevant here. I will take a look at merging them.

Ah, it seems those patches have already been imported in hrev55324, i.e. last August. Please test on a recent nightly to see if this is improved any.

Please post a syslog (for the device details).

Committed in hrev56148, please try with a current nightly.
