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=) 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=, ap=) 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=, eva=) at /usr/src/sys/amd64/amd64/trap.c:851 #5 0xffffffff80d4addd in trap_pfault (frame=0xfffffe3fd0568870, usermode=) 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 ??
