Since genirq, MSI interrupts have their irq_chip descriptor managed by
the IO-APIC support. What remains to be tested is the masking/unmasking
code, which is still implemented by the msi driver; unfortunately I have
no PCI-Express hw at hand anymore, so I can't test CONFIG_PCI_MSI
properly.
At first sight, the issue Mathias raised looks like an out-of-bound
array reference indexed on an unexpectedly large IRQ value; this would
be quite a dumb bug, but the only way to check that is with proper hw.
