Hello,I think that this error message is not about MSI-the-manufacturer but that here MSI stands for Message Signaled Interrupt:
https://www.kernel.org/doc/html/latest/PCI/msi-howto.htmlYou could then try to boot with the pci=nomsi boot parameter to see if your PC boots properly. But there is a chance that this message is an information message about a step of the boot procédure that just has been succesful and that the problematic step that freezes your computer is the next one...
