Michael, I now have MMIO traces after modprobe of wl and b43, both after a fresh cold reboot. There are many similaries (of course), but some differences that could be important in the DMA errors.
In both dumps, I see the code advancing through the cores. I don't see the PCI configuration read/writes, thus I don't see the core selection. Once the SSB_IDHIGH register has the correct value for the 802.11 core, I see the code read the SPROM. In Broadcom's driver, I see additional read/write cycles that do not happen in b43, but I cannot identify the target registers. The operations in question are: read16 base+0x0800 -> 0x2801 write16 base+0x0800 <- 0x3801 read16 base+0x280a -> 0x6dbe write16 base+0x280a <- 0xedbe Any idea what is located at offsets 0x0800 and 0x280a? Nothing in the b43 dump reads or writes either of those locations.
