---------- Forwarded Message ---------- Subject: 4318 misbehaving with bleeding edge kernels Date: Friday 10 July 2009 From: Celejar <celejar@xxxxxxxxx> To: bcm43xx-dev <bcm43xx-dev@xxxxxxxxxxxxxxxx> Hi, I have a 4318 (rev 02), which has been working fine with b43. Recently, with 2.6.31-rc2 kernels from the wireless-testing git repo, I've been having trouble. Sometimes the card simply fails to associate after doing 'iwconfig eth0 essid xxxx'. It doesn't even seem to try; i.e., when it does associate, I see log entries like these: Jul 10 02:25:19 lizzie kernel: [ 318.302652] eth0: direct probe to AP 00:1a:70:f5:76:7e (try 1) Jul 10 02:25:19 lizzie kernel: [ 318.310396] eth0 direct probe responded Jul 10 02:25:19 lizzie kernel: [ 318.310401] eth0: authenticate with AP 00:1a:70:f5:76:7e (try 1) Jul 10 02:25:19 lizzie kernel: [ 318.312273] eth0: authenticated Jul 10 02:25:19 lizzie kernel: [ 318.510040] eth0: associate with AP 00:1a:70:f5:76:7e (try 1) Jul 10 02:25:19 lizzie kernel: [ 318.511947] eth0: RX AssocResp from 00:1a:70:f5:76:7e (capab=0x401 status=0 aid=1) Jul 10 02:25:19 lizzie kernel: [ 318.511952] eth0: associated Jul 10 02:25:19 lizzie kernel: [ 318.513218] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready but often I see nothing in the logs at all, and iwconfig shows "Not-associated". I just keep repeating the 'iwconfig eth0 essid xxxx' command until it finally takes, and then the connection seems to behave normally. When the card is not functioning, trying 'iwlist eth0 scan' initially gives: ~# iwlist eth0 scan eth0 Failed to read scan data : Resource temporarily unavailable and subsequent invocations, when the card is still not working, gives: ~# iwlist eth0 scan eth0 Interface doesn't support scanning : Device or resource busy When the card resumes functioning, scanning works correctly. I have tried both the old and new firmware, with similar results.
