Anyway, it went away in -rc6. Hah, that's a lot more plausible than bcm43xx's drain patch actually causing this. So maybe somehow interrupts for bcm43xx aren't routed properly or something... Ray, please check /proc/interrupts when this happens. I am convinced that the patch in question (drain tx status) is not causing this -- the patch should be a no-op in most cases anyway, and in those cases where it isn't a no-op it'll run only once at card init and remove some things from a hardware-internal FIFO. johannes --=-GYTok38B2melWxge36NU Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iD8DBQBFXzsb/ETPhpq3jKURAm80AJ44eSZHzQHOfpvhKLL3DVH+N2lF3QCgopKQ ZbcPCp+FSe3daOEimqJv4n8= =BC0X -----END PGP SIGNATURE----- --=-GYTok38B2melWxge36NU--
