I've been getting kernel panics when i try to build iwd, a dependency of network-manager. It crashes hard, so there's no recorded log, but I managed to scrape this from an ssh session: $ guix build iwd ... PASS: unit/test-p2p PASS: unit/test-client ./build-aux/test-driver: line 107: 6837 Aborted "$@" > $log_file 2>&1 FAIL: unit/test-arc4 PASS: unit/test-sa When the test-arc4 fails, soon after a kernel panic results and the system freezes. Repeated this multiple times. Going to remove iwd support for network manager locally and then try again. live well, vagrant
