I think you'll also have more problems. > My project has been to update an ARM-based Linux WAP from an older > version of Linux to 2.6.35-ish.

This mailing list sees email from people working for Atheros, but they will basically not help unless you are running latest git code. They also help less with older hardware. There seems to be a strong focus on the very latest x86 platforms, so PCI-only chip on ARM is somewhat of a bad starting position. (Atheros of course wants you to use their SoCs instead.) > I'll work on migrating my project to that version. I'd start by using very latest git. > The problems that I'm still seeing are: For the record I've tried to use similar generation hardware as you, I was on AR5416, but I gave up. After giving up I was motivated to try again, but at that point my PCI bus master had broken. I have new hardware now but too many other construction projects at the moment. > 1.)

I also sometimes see "ath: Failed to > stop TX DMA in 100 msec after killing last frame". I've gotten my share of DMA error messages. My gut feeling then was that they were due to bad driver code, but I have been convinced by members of the list that the driver is by now fairly good, so I guess that instead it may be because of the ath9k driver being firmware bug incompatible with Windows drivers where presumably everything works great. > 2.)

Performance and ability to stay associated is intermittent This was exactly my problem, although I was operating as STA. I had severe problems with AR5416. By the time I got to use AR9220 much I quickly had the broken bus master. I'll try my luck with AR9380 next, although it is quickly becoming too old as well. //Peter _______________________________________________ ath9k-devel mailing list [email protected] https://lists.ath9k.org/mailman/listinfo/ath9k-devel
