Not sure, if this issue has been resolved meanwhile. The thread I found

I ran into this issue, when upgrading Ubuntu from 7.10 (kernel
2.6.22-14) to 8.04rc (kernel 2.6.24-16) and added my findings to bug
219312 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/219312) .

A "pci=nomsi" got this kernel on its feet again, but if there is still
interest in kernel messages or other traces, then please let me know.
Can you please attach full boot log and the result of "lspci -nn"?
