Bordeaux managed to build it, according to 'guix weather
--system=armhf-linux iwd', hence I'm closing this old forgotten issue.
Please reopen if you still experience it on a standard Guix System
kernel.

Thanks,

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
