The user mentioned a segfault when rebooting their Windows VM. Segmentation fault usually points to some kind of memory issue in the program. + +Looking at the logs provided, there are several entries from VFIO and kvm. I know that VFIO is related to device passthrough, which the user mentioned they're using for their tape drive. The error about perf interrupt might not be directly relevant here but shows performance monitoring issues. + +The key line is [315765.858431] qemu-kvm[1385]: segfault at 0 ip (null). That's definitely a crash in the QEMU process. Since they're using PCI passthrough with an MPT SAS controller, the problem might be related to how QEMU handles this device during reboot. + +I recall that VFIO is used for device management in KVM. If there's a segfault upon reboot, it could be due to improper handling of the device state or resources when resetting the VM. The user also mentioned that two identical cards fail the same way, so it's likely an issue with how QEMU interacts with these controllers. + +Other error messages mention issues with the MPT base and SAS initialization. These seem like hardware-related problems but triggered by QEMU during reboot. Since the segfault happens in qemu-kvm, it points towards a kernel module or hypervisor issue rather than user-mode translation errors. + +So, considering all this, the bug is related to KVM's handling of the passthrough device, leading to a crash upon reboot. +</think> + +The bug report involves a segfault occurring during a reboot of a Windows VM using QEMU-KVM. The issue arises with an MPT SAS controller under VFIO-Passthrough setup, leading to kernel errors and failure in initializing the storage controller properly. The key here is that the segfault happens within the QEMU-KVM process, which suggests it's related to how the hypervisor handles the device during reboot or reset. + +Given the context of the error messages pointing towards KVM (kvm: zapping shadow pages for mmio generation wraparound) and VFIO (vfio-pci 0000:1a:00.0), this is likely a kernel module or hypervisor-related issue rather than a user-mode translation problem. + +Thus, the category is: + +**KVM** \ No newline at end of file |
