Side note: In case this is timing-related: the machine in question is a dual-core 1.3Ghz CPU (Core 2 Duo U1400). I think SMP has always been enabled, I don't think I ever tried UP. Also, in addition to the PIO fallback code, that particular mmiotrace test was done with the "udelay(10)" added to the b43_write*() functions. So it was even slower. Maybe the bug only happens on slow machines (and then the udelay obviously wouldn't help!), but that would not explain why mmiotrace might then _hide_ the bug for some people.
