The "Unable to allocate MSI interrupt" might be the immediate problem.

Who belongs to MSI interrupt allocation?  PCI?  ACPI?

However the driver does attempt to handle and recover from the MSI
interrupt allocation error so perhaps that's no the cause at all.

The pci_id says your chip is an L1c.  Jie Yang is the maintainer of  
the atl1c driver and is cc'd.

I'd be curious to know if the lockup occurs when booted with pci=nomsi.
