The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /

An extract of the semantic patch that makes this change is as follows:
Am I interpreting this correctly as having to choose between fast iops

with ata_piix?
Some drives do weird things when NCQ is used and turn off some of their

For several times I tried libata on small machines equipped with either

plain old IDE driver. I realized that all the slower ones were running
Thus, I have implemented the 32-bit mode to bring the performance back

Could you try 2.6.24 or 2.6.25-rc2 with hdc=noprobe parameter?
I'm using a different DVD drive now and I don't have any delays during boot
