ata2.00 timeouts

[Brian C. Huffman]

Running the latest rawhide, I'm getting the following message after the RedHat Nash but before the LVM checks for physical volumes.  I have quiet turned out, but I could turn it off to find out exactly where in the kernel load this is happening:

ata2.00: failed to set xfermode (err_mask=0x4)

It doesn't seem to cause any problems after the machine has booted, but it takes 4 of these messages before it times out and each one takes quite a few seconds resulting in a significant pause in the boot process.

I'm guessing this is known.  Is there anything I can do to help troubleshoot?

Thanks,
Brian
