(-1) [315842.957890] mptsas: probe of 0000:1a:00.0 failed with error -1 The qemu-kvm segfault happens when I issue a reboot on the Windows VM. The card I have is: 1a:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev ff) I have two of these cards (bought with many years difference), exact same model, and they fail the same way. I'm using PCI passthrough on this card for access to the tape drive. This is very easy to reproduce, so feel free to let me know what to try. Kernel 3.10.0-327.18.2.el7.x86_64 (Centos 7.2.1511). qemu-kvm-1.5.3-105.el7_2.4.x86_64 Reporting it here because of the segfault, but I guess I might have to open a bug report with mptbase as well?
