What exactly do you mean by "it doesn't boot completely"?  I compared
the two dmesg logs, and I see that the "with MSI" log also has the
"single" parameter, so it will only boot to single-user mode.

The "pci=nomsi" log does not have "single", so it will boot normally.

But I guess if you omit both "single" and "pci=nomsi", something still
goes wrong?  Do you have a log for that case?
