Subject: Re: ax88179 regression

Absolute last post from me. 

I migrated to a Intel Sandy Bridge based system to test. Definitely something 
going on with the AMD based system, could be power supply/motherboard bios 
related.

On the Intel system the ax88179 still locked up one time.  I rebuilt with for-
usb-linus tree merged and I reverted:

2a100047481a5c7430c72883b586eb6f2df34812 

xhci: remove conversion from generic to pci device in xhci_mem.c

I can't say for sure if this commit is a problem but this kernel build has 
been up now for several hours without an issue and i've put it through paces 
that usually lock up the nic.
