I was recently able to reproduce a bug that sounds related, http://bugme.osdl.org/show_bug.cgi?id=2030 has the details. Would be interesting to know whether the "fix" I found (running _only_ the initialization part of the bcm4400 driver) helps in this case too. Broadcoms changelog provides some clues about what kind of access patters make the chip break. Current guesses are ssb_* (maybe ssb_is_core_up returning 1 even when it isn't leading to ssb_pci_setup not getting called) and b44_setup_phy (where the register access pattern differs slightly). It didn't work even after altering the register access patterns to be ~= identical, making sure ssb_pci_setup gets run etc., alas, but I probably missed something. Anyway, I'm working on it, but no guarantees on when I'll find the time to nail it down. ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
