The Z2 is a typical crazy Sony Laptop - full of insanely over the top technology that will be a bastard to get working.

Installation

I installed Debian testing (Wheezy) from the netinst CD, weekly installer as of 10/2/2011.

I have the PMD (docking station) so I booted the machine plugged in and used the DVD reader to boot the CD.

I resized the Windows partition to make some free space (I'm keeping windows for a moment, at least 'till I've got the GOBI3000 firmware copied and working).

I'm doing manual partitioning because I want an encrypted volume on the fakeraid with LVM on top of that.

The low points:

  1. I didn't install the non-free software, as when I tried the system seemed to hang in the preparation of the partitioner. Perhaps the presence of an USB key troubled it.

  2. When partiions are created on the fakeraid the /dev/ nodes don't get created. I had to do two runs of the installer, creating the partitions in the first run then installing on to them.

  3. The system proposed installing grub on /dev/md, which obviously wont' work, I set it to /dev/md126 by hand.

  4. The GRUB install failed. grub-install is not happy about a fakeraid that's handled by mdadm (it seems it can cope either with a fakeraid handled by dm-raid or a software raid handled by mdadm, but a fakeraid handled by mdadm freaks it out).

    The simple solution is to add a new hard-disk entry to /boot/grub/device.map and rerun the grub installation.

    (hd2)	/dev/md126
    

    (This is Debian bug #659460).

  5. I initialy called my volume-group "coal-vg", (the machine is called "coal"). This is a bad idea as the cryptsetup initramfs hook can't cope with volume group names containing "-", I ended up with a broken system and had to start again.

    (This is Debian bug #659647 and is now fixed).

After upgrading to Sid I've been able to use the the DRI PRIME mechanism to run games on the Radeon GPU in the PMD.
