Comment 6 for bug 1443924

Same problem here. The issue is intermittent - sometimes I cannot even connect after initial boot, and sometimes I stay connected for long stretches.

I found that I can trigger the problem by downloading a large file. After a few megabytes of data, I get a stream of flush errors, then the number of bars I see on the NM applet drop to zero, and a few seconds later I lose connection, and cannot connect again. Removing and reloading rt2800pci module allow me to connect - usually. But attempting the download will repeat the above symptoms.

One final bit of information: when I boot using pci=nomsi parameter, I still get the flush errors and the download pauses a bit, but then it recovers and continues the download. I get between 50-100KB/sec average and intermittent connectivity problems with this flag, but I haven't lost connection to my AP yet.
