Re: an0: device timeout on x31

[Jost Tobias Springenberg <jspringe@xxxxxx>]

Hi there,
ok I found a patch that was kind of ok somewhere on a freebsd mailing list.
The patch works and I can ping without any problem, initializing a ssh session also works.
However at some time after switching wlan on and transferring a file i.e. the system simply freezes.
No dropping to kernel debug console or the like.
Any ideas on that one ?

Greetings,
Tobias
