Yes I did an initdb on $HOME/var/pgsql/data, that wasn't it.

After consulting the irc channel I was shown a workaround:
In postgresql.conf I had to explicitly set 'wal_sync_method = fsync' (which
was commented out), for whatever reason the default was causing the panic.

This is after a new Ubuntu 10.10 install,
mount:
/dev/mapper/myname-root on / type ext4 (rw,errors=remount-ro,commit=0)
