Comment 49 for bug 352150

Ok, then your and my bug appear to be different. With some kernels/drivers I were able to reach more than 30MBit/s, and then the firmware errors got very frequent. Newer kernels/drivers only reach about 28MBit/s and firmware errors are rare. So I speculated that there is a kind of workaround built-in now.

As your symptoms are different, I will open a new bug if mine get more annoying again.
