Hello Maciej,
24.06.2021 2:38, Maciej W. Rozycki:

With
linux-x86-pirq-router-sis85c503.diff applied
linux-x86-pirq-router-sis85c497.diff applied
and DEBUG 1 in arch/x86/include/asm/pci_x86.h
here is new log:
https://pastebin.com/n3udQgcq
My feeling is that something went a bit wrong because:
8139too 0000:00:0d.0: can't route interrupt
and
# 8259A.pl
irq 0: 00, edge
irq 1: 00, edge
irq 2: 00, edge
irq 3: 00, edge
irq 4: 00, edge
irq 5: 00, edge
irq 6: 00, edge
irq 7: 00, edge
irq 8: 00, edge
irq 9: 00, edge
irq 10: 00, edge
irq 11: 00, edge
irq 12: 00, edge
irq 13: 00, edge
irq 14: 00, edge
irq 15: 00, edge
Note: I still used 4.14 kernel for this test but your patches applied
cleanly with no fuzz so I suppose it should be ok.
Thank you,
Regards,
Nikolai
