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:
