Panic with 2.6.19-rc3-ga7aacdf9: Invalid opcode at acpi_os_read_pci_configuration

[Giacomo Catenazzi <cate@cateee.net>]

Since few days I have this bug (not sure if it
caused by changed configuration or if it is a regretion).
The fololowing trace is from last git.
Captured with serial console, so I see some extra empty lines.

ciao
