I see your patches for this chipset have now arrived and I'll test them as soon as I get to that box. Meanwhile I've captured a similar log from another (and actually this one is my main concern because it can not be replaced easily): https://pastebin.com/NVfRcMww Something is clearly different here, 8259A.pl reports all irqs are edge no matter what. BIOS setup only offers some strange "PCI IDE IRQ mode" (Edge/Level) and apparently it has no effect anyway. (A modified version of 8139too works fine though) Thank you, Regards, Nikolai > It does PCI interrupt steering, it has the ELCR, but we don't have a PIRQ > router implemented for it.
