[Message part 3 (text/plain, inline)]

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

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,

Maxim
