The fix is not easy. In fact, it's as hard as to fix it by implementing a feature that allows to use different rate control algorithm for each device. Given the fact the problem doesn't occur in normal conditions, it's a low priority for me (unless there is a volunteer to fix it). It needs to be fixed before d80211 is merged, though (sigh). > # modprobe rt2500pci > > Loading module: rt2500pci - CVS (N/A) by http://rt2x00.serialmonkey.com. > ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 21 (level, low) -> IRQ 18 > wmaster0: Failed to select rate control algorithm > wmaster0: Failed to initialize rate control algorithm I suppose you don't have automatic loading of modules enabled, right?
