https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193500 --- Comment #9 from jan.kokemueller@gmail.com --- So to clarify, setting "hw.drm.msi=0" is fine as a workaround. When hw.drm.msi is set to 1, I have to do one suspend/resume cycle for the interrupts on irq16 to stop. Then the GPU uses irq260. hw.drm.msi=1 (after suspend/resume): interrupt total rate irq1: atkbd0 2085 2 irq9: acpi0 15696 18 irq12: psm0 85609 100 irq14: ata0 21899 25 irq15: ata1 594 0 irq16: uhci0 3080356 3619 irq20: hpet0 171708 201 irq23: uhci3 ehci1 168 0 irq256: hdac0 113 0 irq258: iwn0 42571 50 irq259: re0 24 0 irq260: vgapci0 33092 38 Total 3453915 4058 -- You are receiving this mail because: You are the assignee for the bug.
