I snapped some screenshots, but can't associate using laptop's iwn(4) (in stable/11, stable/12, or head/13) at the place I'm currently staying. (I may be able to at least get the screenshots uploaded to the Web server later on today.) But since I was able to get a dump, they are probably not very interesting. It looks (to my semi-trained eye) as if iflib is implicated -- partly because the backtrace mentions it (ref. frame #14 from the backtrace in core.txt.8), and partly because I only saw the panic on my laptop, the wired NIC for which is em(4), while my build machine (which uses rl(4)) had no issues. I'm happy to poke and/or test, but will need some direction to do so. Peace, david --=20 David H. Wolfskill david@catwhisker.org Women (and decent men): vote against supporters of Trump's misogyny!
