dialogue won't start, high cpu usage

[Brett Holman]

I connected the system to wifi using gnome's settings.

Stuck at the "Preparing Ubuntu..." screen burning 100% cpu on one core.

The process burning CPU (currently at 27m runtime) is:

python3 -m subiquity.cmd.server --use-os-prober --storage-version=2 --postinst-hooks-dir=/snap/ubuntu-desktop-bootstrap/107/etc/subiquity/postinst.d

strace shows no output when run for several seconds, so no syscalls in the hot loop

I generated a core dump of the running process using GDB, but at 627M I don't think it is going anywhere. When I attach with gdb I see:

0x00007f23d27ce5bb in nl80211_get_ie (ie=0 '\000', ies_len=<optimized out>, ies=<optimized out>) at probert/_nl80211module.c

warning: 378 probert/_nl80211module.c: No such file or directory

Could you provide the logs from /var/log/installer/ please? I've yet to run into this on my tests.
