    SubjectRe: "irq/matrix: Spread interrupts on allocation" breaks nouveau in mainline kernel
    From
    Date
    Hi, please ignore the warning: it happens before and after the regressing
    commit (I didn't actually mean to include it on the log I gave here, whoops).
    As for how I determined nouveau is getting assigned the same IRQ vector as
    another device, I checked using /sys/kernel/debug/irq. Additionally; when
    nouveau does initialize properly after resume (e.g. after reverting this
    patch) I see it get assigned a seperate vector from the other devices.
