https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203746 Bug ID: 203746 Summary: Panic in NVME driver Product: Base System Version: 10.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: mgoroff@quorum.net Created attachment 161991 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=161991&action=edit Crashinfo file for NVME kernel panic We are running a ZFS filer server using 10.2-RELEASE. We recently encountered a kernel panic from the NVME driver under heavy load with an Intel DC P3700 NVME SSD board as a ZIL and an L2ARC. The core.txt file from the crash dump is attached. All NVME sysctl params were left at the defaults. The stack trace from the crash dump is: (kgdb) #0 doadump (textdump=<value optimized out>) at pcpu.h:219 #1 0xffffffff80948642 in kern_reboot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:451 #2 0xffffffff80948a25 in vpanic (fmt=<value optimized out>, ap=<value optimized out>) at /usr/src/sys/kern/kern_shutdown.c:758 #3 0xffffffff809488b3 in panic (fmt=0x0) at /usr/src/sys/kern/kern_shutdown.c:687 #4 0xffffffff80d4aadb in trap_fatal (frame=<value optimized out>, eva=<value optimized out>) at /usr/src/sys/amd64/amd64/trap.c:851 #5 0xffffffff80d4addd in trap_pfault (frame=0xfffffe3fd0568870, usermode=<value optimized out>) at /usr/src/sys/amd64/amd64/trap.c:674 #6 0xffffffff80d4a47a in trap (frame=0xfffffe3fd0568870) at /usr/src/sys/amd64/amd64/trap.c:440 #7 0xffffffff80d307f2 in calltrap () at /usr/src/sys/amd64/amd64/exception.S:236 #8 0xfffff8345ad7aaa8 in ??
