https://bugzilla.kernel.org/show_bug.cgi?id=217247 Bug ID: 217247 Summary: BUG: kernel NULL pointer dereference, address: 000000000000000c / speculation_ctrl_update Product: Virtualization Version: unspecified Kernel Version: 6.1.20 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: hvtaifwkbgefbaei@xxxxxxxxx Regression: No Created attachment 304023 --> https://bugzilla.kernel.org/attachment.cgi?id=304023&action=edit kernel config This is 6.1.20 with only ZFS 2.1.9 module added. I booted kernel with acpi=off because this old Ryzen 1600X system is getting unreliable (so only one CPU is online with acpi=off, and it has been reliable before this splat). 2023-03-25T13:28:40,794781+02:00 BUG: kernel NULL pointer dereference, address: 000000000000000c 2023-03-25T13:28:40,794786+02:00 #PF: supervisor read access in kernel mode 2023-03-25T13:28:40,794788+02:00 #PF: error_code(0x0000) - not-present page 2023-03-25T13:28:40,794790+02:00 PGD 0 P4D 0 2023-03-25T13:28:40,794793+02:00 Oops: 0000 [#1] PREEMPT SMP NOPTI 2023-03-25T13:28:40,794795+02:00 CPU: 0 PID: 917598 Comm: qemu-kvm Tainted: P W O 6.1.20+ #12 2023-03-25T13:28:40,794798+02:00 Hardware name: To Be Filled By O.E.M.
