Kernel 3.13 is OK. Can anyone with a 4331 confirm that PHY transmission errors are a lot more prevalent with either mainline 3.14-rc1 or the current wireless-testing than with 3.13? I do not have that particular device, but I do not see any changes for my 14e4:4315; however, the 4331 has a different PHY than does the 4315. A review of the commits between 3.13 and 3.14-rc1 shows nothing for bcma that should cause this effect. For b43, the only one that might cause this is commit 64e5acb entitled "b43: fix the wrong assignment of status.freq in b43_rx()". That was clearly a bug and it fixed thing for my system, but we must consider if that bug was also masking some other problem that is now revealed. I have asked the bug reporter at b.k.o if it is possible to bisect the problem. Larry
