I'm quiet sure that it hasn't anything to do with ATA, I used ata-mkIII before 
on RELENG_5 on that mixed MBR/GPT box.

Well, it was one of my testboxes, although I haven't expected the upgrade to 
disable the box it's not that problem. The problem is that I want to have 
-current on it without changing my disk layout, booting from MBR label and 
having everything else on GPT slices. 8 labels per slice are not enough on 
that testbox!
And every GPT partition holds more or less important data....
And I need current to test it, whether it is stable enough to run my webserver 
since I need nullfs at sensible performance, which RELENG_5 doesn't provide
And if it fits my needs. this box will act as PXE installer... Hmm, it's more 
important than I thought....

Thanks,

-Harry
