I do not know about your MUA, but mine has a "Reply all" button, which
sets the references correctly as well, and allows to add new addresses
to the mail.

The point is, you can not expect everybody which reads your post, and
which would find your post in the archives to remember what platform you
use. So, either use the "reply" function of a MUA so that mine allows me
to find back the context, or repeat what is your setup every time you
post to the mailing list.

Ok. Try adding a call to xnarch_trace_panic_freeze() before the call to
show_stack.

Right, primary mode is a term specific to user-space threads.

P.S: The next private mail you send me will receive no answer.
