Device will sometimes not boot

[Theuns-Botha]

When deploying https://github.com/Theuns-Botha/grisp_wifi_connect to my grisp_base device, using sudo mix grisp.deploy, the boot procedure starts hanging without any additional information after the following message in the:

notice: wlan0: link state changed to UP
wlan0: Associated with b0:89:00:25:20:e0
err: wlan0: ipv4_sendrawpacket: No buffer space available
afatal extension: source=0, is_internal=0, error=30

Note that I see this message in the terminal that I open over the serial connection.

This does not happen all the time, I sometimes get successful boots after a few retries.

Note that I deliberately excluded my wpa_supplicant.conf file from the commit.
