Public bug reported: This is the second time (unclear about a third one) I encounter this crash and all I could do was power-cycling to reboot.
/var/crash is empty /var/log/syslog and /var/log/kern.log don't contain any hint around the crash time (the subsequent reboot is present though). So I took a picture (attached) :-} The last time this bug occurred, I was destroying a juju env with 13 lxcs instances but I've since done it again without reproducing the issue (and I do it on a ~regular basis without triggering the bug). Hopefully the traceback can provide some hints ?
