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

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 -------------------------------------------------------
