Yeah the kernel will boot but the hd performance is sh*t on my laptop. I
am running FC6 with
kernel 2.6.21 and without the combined_mode setting my disk performance

whopping 1.25mb/sec from 44mb/sec when I boot with combined_mode=libata.
Then something is very wrong with the way you are setting it up, or the
current code. Please post a dmesg booting with libata driving all your
disks and it can get fixed before 2.6.22
Do you happen to know how FC7test4 behaves on your box btw
I did the upgrade last night. Drive performance was SLLOOWW. When it
came time to the reboot, I had a corrupted disk. (Not certain if that was
the fault of the upgrade. I have to finish the fsck repairs first.) And
this is with ext3. Not good.
I have been seeing real bad driver performance on the latest FC6 kernel as
well.
