Subject: ata4294967295: failed to start port (errno=-19)

Got the message about ata4294967295 - looks like an uninitialzed 
variable or negative wrapraound. This is PIIX4 class ide on 440BX based 
laptop (Thinkpad X20). Everything seems to work fine though, there is 
only one PATA HDD attached and it works fine.

This message comes from 2.6.24-rc3 + todays git, version 
a531a141089714efe39eca89593524fdf05104f2. I did grep the logs and found 
that it first appeared in 2.6.24-rc1 (+ some git mayve) on Nov 3. 
I used 2.6.23 before that and it did not show this message.

Full dmesg:
