Title:
segfault upon reboot
Status in QEMU:

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?
