I have a crash report to provide (for RELENG_8 dated 2010/02/12), but I'd like to know who's maintaining ath(4) at this point in time. I also need to discuss a commonly-reported issue with AR5416 and/or AR9280 cards (e.g. D-Link DWA-552 running in 802.11g mode w/ WEP) spitting out "stuck beacon" errors, which are what I was trying to resolve when the kernel crashed. (I induced the crash, but I'm not sure exactly why/how). Given that the issue has existed for years now... http://www.daemonforums.org/showthread.php?t=3388 http://forums.freebsd.org/showthread.php?t=5983 http://forum.pfsense.org/index.php?topic=21374.0 http://forum.pfsense.org/index.php?topic=32041.0 http://www.broadbandreports.com/forum/r25070916-FreeBSD-MIPS-dev-Adrian-Chad-on-stuck-beacon-issue http://forums.freebsd.org/showthread.php?t=22112 (recent & thorough!) ...and "bintval 1000" does not solve it, let's work together to find a solution. If you need hardware I will be more than happy to buy you (brand new) cards which you can keep. If you have beta/test drivers and/or can provide *thorough* debugging instructions, I will be more than happy to do what I can. I'll also point out the Linux madwifi folks have an *entire page* dedicated to this problem, which is quite interesting: http://madwifi-project.org/wiki/StuckBeacon If a workaround or solution isn't plausible, what cards do people actually recommend that work reliably / have reliable drivers? I was under the impression Atheros cards were reliable/decent compared to, say, Broadcom. Is iwn(4) reliable? -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
