IRQ 16 nobody cared : no solution?
by camerabambai from LinuxQuestions.org on (#53MFD)
I'm on a Slackware-current, latest kernel (5.4.41) on Microserver Gen8 with Xeon dual core cpu.
Work fine all, even the vfio passtrough with qemu and libvirt, only one problem, if I reboot or shutdown the virtual machine give me a panic(host works fine, but If I want to re-run the vm I have to reboot the host).
