With that patches we follow specs and (as recently proved by MMIO dumps) wl. The more important patch is the first one. It detects problem (and warns) with SSB when it is in some broken state. We can for example hit such an issue when enabling DMA on 14e4:4329 (N-PHY, rev 1). The real fix is now known yet, but not we at least get warning. Switching to PIO on that card does not raise warning anymore (as expected). We all hate regressions and Michal says than enabling/disabling SSB device can be tricky. I have tested that patches with few b43 driven devices: 14e4:4318 (BCM4318) 14e4:4315 (BCM4312) 14e4:4329 (BCM4321) 14e4:4328 (BCM4321) 14e4:432b (BCM4322) With each device I performed cold booting, loading b43, testing, bringing interface down and up, testing, reloading, testing. Sometime even more. Unfortunately I do not have aany other SSB devices, like that supported by b44 or gige (OK, I did not even hear about gige earlier).
