Put ATH_ENABLE_11N in your kernel config. This helped, thank you. Message storm is gone. It seems I've been stripping GENERIC overly aggressively.

This way, in-kernel ath_pci(4) would obey kernel config, yet module will always have them by default. As a bonus, this would allow to build it with simply calling make(1) from the module directory. I may eventually do that. I'm just wary of it all because various ABI changes occur with different options and I don't want people bitten by that. (I really should just up the default set of tx/rx buffers; that'd at least fix the error.) -adrian ___ freebsd-wireless@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to freebsd-wireless-unsubscr...@freebsd.org

Re: AR9462 PCIe1x card: endless messages in dmesg
Nope, because kernel modules need to pick up options from opt_xxx.h, and there's a lot of them. (other modules do it by picking defaults; but the wifi infrastructure has a lot of options.) -a ___ freebsd-wireless@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to freebsd-wireless-unsubscr...@freebsd.org
Re: AR9462 PCIe1x card: endless messages in dmesg
Put ATH_ENABLE_11N in your kernel config. Oh and if you build modules, build it with make buildkernel, no cd /usr/src/sys/dev/modules/ath; make. -a On 21 January 2015 at 01:20, Alexey Dokuchaev da...@nsu.ru wrote: Hi there, Just installed this AR9462-based PCIe (1x) card into my work i386 desktop running fortnight-old -CURRENT (r276691).

Oh and if you build modules, build it with make buildkernel, no cd /usr/src/sys/dev/modules/ath; make. Everything I've reported thus far was with kernel and modules built with make buildkernel (and no local patches applied), but I'll keep a note. That said, it would be nice to rebuild ath(4) with cd .. make like you're mentioned. Can we expect it one day? ;-) ./danfe ___ freebsd-wireless@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to freebsd-wireless-unsubscr...@freebsd.org
