wpa_supplicant: atheros up & down like a yo-yo, interrupt storms too
Hi
First post since moving from BSDForums... I have a new FreeBSD 7.0 STABLE build on my Dell Inspiron 8600 laptop, retro-fitted with an Atheros 5212 wifi card. As soon as I start wpa_supplicant I get this in .../messages: ... ... Jun 15 23:03:03 aurora kernel: ath0: link state changed to DOWN Jun 15 23:03:06 aurora kernel: ath0: link state changed to UP Jun 15 23:03:08 aurora kernel: ath0: link state changed to DOWN Jun 15 23:07:15 aurora kernel: ath0: link state changed to UP Jun 15 23:07:18 aurora kernel: ath0: link state changed to DOWN Jun 15 23:07:19 aurora kernel: interrupt storm detected on "irq9:"; throttling interrupt source Jun 15 23:07:21 aurora kernel: ath0: link state changed to UP Jun 15 23:07:24 aurora kernel: ath0: link state changed to DOWN Jun 15 23:07:26 aurora kernel: interrupt storm detected on "irq9:"; throttling interrupt source Jun 15 23:07:26 aurora kernel: ath0: link state changed to UP Jun 15 23:07:29 aurora kernel: ath0: link state changed to DOWN Jun 15 23:07:32 aurora kernel: ath0: link state changed to UP Jun 15 23:07:35 aurora kernel: ath0: link state changed to DOWN Jun 15 23:07:35 aurora kernel: interrupt storm detected on "irq9:"; throttling interrupt source Jun 15 23:07:37 aurora kernel: ath0: link state changed to UP Jun 15 23:07:40 aurora kernel: ath0: link state changed to DOWN Jun 15 23:07:40 aurora kernel: interrupt storm detected on "irq9:"; throttling interrupt source Jun 15 23:07:42 aurora kernel: ath0: link state changed to UP Jun 15 23:07:45 aurora kernel: ath0: link state changed to DOWN ... ... Continually checking ifconfig ath0 shows that the connection associates for a few seconds then drops and scans various alternative channels before eventually associating then dropping again, ad infinitum. Running wpa_supplicant manually just generates an endless stream of stuff. Any suggestions to help solve or isolate the problem? Curiously WPA worked on this exact hardware without any problem when I previously tried PCBSD 1.4 (FreeBSD 6.2, I believe).

does it do the same if you use GENERIC?
|
|

Had the same problem some time ago. Please keep us up to date if you managed to fix it.

Thanks, yeah just built GENERIC today with the same /src revision. Same problem.
Strange thing is, when testing FreeBSD 7-RC on a totally different PC (nForce2 mobo) I had exactly the same problem with the onboard nVidia LAN (nfe). Never solved that either. So I have to wonder, why do I get this on two completely unrelated setups, and yet there doesn't seem to be many other people reporting it? sim |

I have the same issue with a 5212 card. I wasn't able to get it to work reliably with 6.x, unlike you. There do appear to be changes in ath_hal and ath in the code for 8.0 . You might want to see if that works better.

you could try updating your HAL src from madwifi drivers or sam's revised linux drivers and recompiling your kernel, but even thats hit and miss depending. |
