Hi
The patch 0e4c2eeb758a91e68b9eaf7a4bee9bd5ed97ff2b ("alpha/PCI: Replace
pci_fixup_irqs() call with host bridge IRQ mapping hooks") breaks
networking on Alpha for me. I have an Alpha Avanti server with tulip
network card.
The patch 0e4c2eeb breaks it so that I get MCE when the network card
driver is loaded. The patch 814eae59 fixes the MCE, the system boot
completes, but the network card doesn't receive any interrupts (and soon
it reports warning about timeout on tx queue). All kernels in the 4.14
branch have this bug.
