Public bug reported:
Binary package hint: pciutils
Under 32-bit hardy (a colleague has also confirmed this behavior in
64-bit karmic), "lspci -xxxx" does not display the extended
configuration space, stopping after only 16 lines of output. As a
demonstration, here's the output that results from probing my graphics
card (a PCI-E 2.0 device):
clio:~ % uname -a

If I carry out this same exercise on a machine running CentOS, I get the
expected 256 lines of output:
-bash-3.2$ cat /etc/*-release

On the system running Ubuntu, I have also tested the latest release of
pciutils (3.1.7), with the same result as the pre-installed package:
clio:pciutils-3.1.7 % sbin/lspci --version
lspci version 3.1.7
clio:pciutils-3.1.7 % sudo sbin/lspci -s 01:00.0 -xxxx
