Did you actually try my suggestion?

Yes ("libata.fua=1" is ok I think, or it should just be "libata.fua"?):
[ 0.000000] Kernel command line: root=/dev/sda6 ro vga=0x305 libata.fua=1
[ 285.004166] ata1.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x2 frozen

Is libata built into the kernel, or a module?

If it is a module, using the kernel command line won't work.
