https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193399 Bug ID: 193399 Summary: Fatal trap 12: page fault while in kernel mode (g_resize_provider_event -> g_slice_orphan -> free) Product: Base System Version: 10.0-RELEASE Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: stepan.tezyunichev@gmail.com Created attachment 146970 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=146970&action=edit Auto-generated core.txt file I have a FreeBSD based SAN running on vmWare virtual machine. There are two disk controllers: built-in Intel Patsburg 6 and LSI logic. Both attached to VM using hardware passthrough. There are three iSCSI targets on ZFS raidz2 published by using ctld. Recently I got a problem with one of the disks. After several reboots I executed 'zpool scrub tank'. At that moment system hanged and kernel panic was generated. Please find attached auto-generage core.txt report. I can upload vmcore if required.
