It solved one issue with the IOMMU problems.  The second issue I'm having may 
or may not be related.  After I applied the patch I left iperf on to transfer 
100GB over wireless to stress test.  When I woke up the next morning, it 
exhibited the same problem of all interfaces not functioning (but restored when 
rmmod rtl8192se) but there were no IOMMU errors or any errors really besides 
cryptic messages in kern.log:
Mar 23 10:28:56 server kernel: [23319.482507] rtlwifi: &&&&&&&&&del entry 5
Mar 23 10:32:32 server kernel: [23535.368946] rtlwifi: &&&&&&&&&del entry 4
I've since been testing whether it's time or transfers that cause the new issue 
as the old issue would pop up an hour or so because it was beacon count that 
triggered it.  So far, I've left the interface on and idle for several days and 
it hasn't crashed.  I'm retesting transfer tonight and will get some results 
tomorrow as to what may be causing the second issue.
