05:31 PM cradek: anyone familiar with this on startup? it happens often, sometimes several times in a row. trying again eventually works.
05:33 PM cradek: this is on busywait6 branch
05:35 PM andypugh_: I (we) changed hm2_eth yesterday. Is this a new problem?
05:36 PM cradek: nope
05:40 PM JT-Cave: what did you change?
05:42 PM andypugh_: Nothing? (Confused!) https://github.com/LinuxCNC/linuxcnc/commits/master
05:44 PM andypugh_: But here it shows as merged: https://github.com/LinuxCNC/linuxcnc/pull/2271#issuecomment-1383118297
05:44 PM JT-Cave: just added support for a different board it seems
05:45 PM andypugh_: Yes, but why can’t we see it at the first link?
05:45 PM andypugh_: (Oh, I just missed it)
05:45 PM andypugh_: https://github.com/LinuxCNC/linuxcnc/commit/bbe9563e327d30eb5a09d5312fbf68aa4c116639

05:55 PM seb_kuzminsky: cradek: can you use strace to see what system call is failing?
05:59 PM cradek: hm lemme try
06:00 PM seb_kuzminsky: :q
06:00 PM seb_kuzminsky: oops
06:34 PM cradek: finally got it to run under strace, and now it doesn't want to fail
06:38 PM cradek: seb_kuzminsky: the answer to your question is no, unfortunately
06:38 PM cradek: because it wants to mess with iptables, it needs to be run sudo with the "fallback" rtapi uid, and that seems to maybe affect the problem
