This happens on master. But I guess, it also fails on 3.6, but I haven't tried!
IIRC, I had a similar problem with "ale" on an ASUS EEE book a few years ago, but I might be completely wrong here.

The commit fixes this bug:
http://gitweb.dragonflybsd.org/dragonfly.git/commit/a45385fec09b660facc3bf5e0abcdfbef1ee216e

Tested on Lenovo X121e with Atheros AR8151 v2.0 PCIe Gigabit Ethernet controller.
Untested on ASUS EEE as it's no longer around.

Note that on the Lenovo the AR8151 controller would hang the system a few seconds after the cable is unplugged. Unplugging the cable and replugging it now works :)

Should this be MFC'd?

#6 Updated by mneumann over 2 years ago

yes, it should be safe to MFC. but probably there are not many alc0 users out there :)
