Will it boot with the "pci=nocrs" option?  If so, please open a
report at https://bugzilla.kernel.org, mark it a regression, assign
it to me, and attach the complete dmesg log.  And please respond to
this thread with a pointer to the bugzilla.

Otherwise, a complete console log should have a clue.  The best
thing would be a log from a serial console or netconsole, with
"ignore_loglevel".

Thanks a lot for your report!
