JFYI.

In reply to [1], I checked the pata-cmd64x driver on my Ultra 10, with the 
results below.

Cheers,

Initially I compiled the driver into the kernel and booted without
initrd; that failed.
I then compiled it as a module and used an initrd for the boot; this
booted without any problems. CD drive seems to work fine too.

Guess I must have forgotten to enable something for the first case;
probably the fact that I had scsi generic, disk and maybe target support
modular? Should the kernel config check for that?

Attached the dmesg for the boot and an lspci -nn.

IMHO the dmesg lies a bit:
   sd 0:0:0:0: [sda] Attached SCSI disk
Despite using a PATA driver, they are _not_ scsi disks...

Timing info from hdparm is similar for both drivers.

> Good tests would be to unpack big archives and then verify them

I created a gzipped tarball of my ~ (about 700MB) and then extracted that
to a separate directory.
A diff between the two trees showed no strange differences.

So, good news I guess :-)

Cheers,
FJP
