Re: 14e4:4315 DMA Errors (still)
Hi Gábor, Charlie, All: I tried wireless-testing commit b4d3a7.. This kernel seems to work more reliably, but only a little. Sometimes, I still get DMA errors on cold boot, and I still always get DMA errors after a suspend/resume cycle. Like Charlie, 'NOHZ: local_softirq_pending 08' shows up when it does manage to connect.. I certainly wish I could report the other successes Charlie has. Perhaps I'll update my wireless-testing tonight and try again.

No, it'll happen pretty frequently the first time I try to connect, but always after I suspend+resume. And once the DMA error pops up, It just keeps happening.. By far, the rarest occurrence is the device actually working. Lance One thing I can see from the log is that you have both wl and ssb (b43's backend) loaded at the same time. Remember to also unload ssb when you unload b43. Also, could you try the real wireless-testing?

Fedora is about to release F12 with a 2.6.31 kernel, and it would be great to be able to backport a fix. I'm a git noob, but I don't see how to bisect between the wireless-testing tree and compat-wireless. Lance, you wrote that if you cold boot, then 'sometimes' you can connect.
