Hi Arend, I've inquired about this issue on the list once before, but I thought I'd try once again to see if Broadcom can offer any suggestions. Recent MacBook Pros with BCM4331 wireless have a strange problem. Tx doesn't work after S3, but only if no external power is applied during the resume. mac80211 reports mostly timeouts for responses to probe requests, but analysis with wireshark shows no frames from the BCM4331 on the air. The only way I've found to recover is to reload both b43 and bcma; reloading b43 alone is not enough. I've checked the values of MACCTL and the DMA TXCTL registers, since these are the ones used by brcmsmac to mute tx, but those look okay. Any suggestions of other things to check? My next step would be to start looking at the state of the phy and radio, but since we don't have much information about what the registers there actually do some suggestions would be helpful.
