kernel-2.6.16-1.2069_FC4 sata panic

[Jerry Williams]

I installed the new kernel-2.6.16-1.2069_FC4 and my machine starts to boot
and then says:
ata1: failed to set xfermode, disabled
ata2: failed to set xfermode, disabled

Then it complains that it can't find any volume groups, there is one, but I
don't think that it can see my SATA disks.  It prints out a few more things
and panics.  I am running Fedora Core 4, planning on going to 5 after it has
settled some.  

Grub kernel line:
kernel /vmlinuz-2.6.16-1.2069_FC4 ro root=/dev/V0/L1 acpi=off rhgb quiet

Should I try something else on the kernel command line?
Thanks!
