I m using Debian 7.0, 7.X and 8.1 distro, when I run fio with Linux nvme driver on DELL R720/R820 server with 64 cores I see soft lockup.
Attached the kernel log which was taken on Debian 8.1 OS (R820) with inbox driver version0.9. Can you please help me analyze this issue. I m not seeing this issue on any other distributions like RHEL, Ubuntu, SLES or fedora.
