Hmm...yeah, I've followed these steps: Fresh CentOS 7.5 install yum install git libmnl-devel elfutils-libelf-devel kernel-devel @development-tools git clone https://git.zx2c4.com/WireGuard cd WireGuard/src make make install deploy /etc/wireguard/wg0.conf systemctl start wg-quick@wg0 kernel panic.
Any additional debugging steps I can provide? This trace looks a little different, so also including it: [ 1571.621740] ------------[ cut here ]------------ [ 1571.627195] WARNING: CPU: 1 PID: 264 at arch/x86/kernel/smp.c:127 native_smp_send_reschedule+0x65/0x70 [ 1571.637324] Modules linked in: wireguard(OE) ip6_udp_tunnel udp_tunnel bonding skx_edac intel_powerclamp coretempd [ 1571.715278] CPU: 1 PID: 264 Comm: kworker/1:2 Tainted: G D OE ------------ 3.10.0-862.2.3.el7.x86_64 #1 [ 1571.726478] Hardware name: Dell Inc.
