Drain the Microcode TX-status-FIFO before we enable IRQs.
This is required, because the FIFO may still have entries left
from a previous run. Those would immediately fire after enabling
IRQs and would lead to an oops in the DMA TXstatus handling code.

Chris,

We have a report of a regression between 2.6.19-rc3 and -rc5. As this patch seems to be the only one that could cause the problem, please pull it from -stable while we sort out the difficulty.

Thanks,

Larry
