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.
