3.14.2 - dmesg report

I've a Dell XPS 13 (ivy bridge, 2013 version) and I've bought an ASIX AX88179 USB 3.0 Gigabit Ethernet I'm using in one of the XPS's USB 3.0 port.

The kernel driver for the ASIX AX88179 appeared with the 3.9 kernel version.

I used the Ethernet adapter for the first time when the 3.10 kernel was released (I'm running ArchLinux which is in rolling release). At that time, transferring a huge number of files or pretty heavy files caused kernel panic: either I had a stacktrace displayed or the computer became completely unresponsive.

Tests performed on another machine, a Dell XPS 17 (L702X), gave the same results, while on Windows no problem so far. Testing with another adapter from another revision gave the same problem.

The disconnection with the Ethernet adapter is more likely to happen when transferring a huge number of files (e.g. several kernel sources with several 10k of files in it). After some disconnections-reconnections, the computer refuses to reconnect again, the adapter doesn't answer anymore, while the link led is still blinking like mad. I've do unplug the adapter and reconnect it again to recover my connection.

It appears the bug is known in upstream, but has not been solved so far: https://github.com/FreddyXin/ax88179_178a/issues/6

Please find as attachment what dmesg reports (on kernel 3.14.2) from the moment I connected the adapter until the adapter completely fails to responds at all.
