In looking to update to the newest system, I’ve downloaded the stable image, flashed to USB, etc. On bootup though, there are some warnings like “watchdog: BUG: soft lockup - CPU #2 stuck for 22s! [kworker/u8:5:191].” It continues a bit, but finally gets stuck with some stack traces and finally waiting on network preconfig “A start job is running for net preconfig (2min 13s / no limit).” I know my ethernet network is working (when I boot from my SSD). I’ve let it run for quite a while (18 minutes) with no improvement.
I’ve tried a couple different USB sticks. This is on a Z710A motherboard, i5-6600k cpu. It’s all pretty standard stuff that should run any Linux. I poked into recovery mode, enable networking, and the networking works just fine from a shell there. After exiting recovery mode and resuming normal booting, it loses the net connection and my DHCP sees no further requests for an IP address.
