https://bugzilla.kernel.org/show_bug.cgi?id=207489 Yani Stoyanov (yaweb@xxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |yaweb@xxxxxxx --- Comment #16 from Yani Stoyanov (yaweb@xxxxxxx) --- Kernel 5.8+ on Fedora 32 I have the same issue with macos (sierra and catalina) virtual machines with passed through gpus. What I do to identify the problem: Try adding different cards to the mac vm's no matter amd/nvidia the vm hangs and if you try to restart/force restart it the whole libvirt process hangs. I get the same kernel overflow as mentioned in the bug. How I am sure its the same problem: I checked out the kernel source comment the problematic: if (edge && kvm_apicv_activated(ioapic->kvm)) ioapic_lazy_update_eoi(ioapic, irq); Rebuild the kernel and try with my version and it was working fine. I also try kernel 5.5.19 where it was fine also since it didn't have the check. I assume macos have some special way of treating the interrupts but since I am new to the linux kernel and linux as hole I can not identify what exactly case the problem. -- You are receiving this mail because: You are on the CC list for the bug.
