This probably is related to the way the ISA IRQs are handled.
Here's a list of commits to revert, in this order:
f7eca374f000 ACPI,PCI,IRQ: separate ISA penalty calculation
487cf917ed0d Revert "ACPI, PCI, IRQ: remove redundant code in acpi_irq_penalty_init()"
4a6e68bf96c1 ACPI,PCI,IRQ: factor in PCI possible
54794580f594 ACPI,PCI,IRQ: correct operator precedence
9e5ed6d1fb87 ACPI,PCI,IRQ: remove SCI penalize function
1fcb6a813c4f ACPI,PCI,IRQ: remove redundant code in acpi_irq_penalty_init()
5c5087a55390 ACPI,PCI,IRQ: reduce static IRQ array size to 16
103544d86976 ACPI,PCI,IRQ: reduce resource requirements
Please try to revert the first 5 first and see if that helps.
