This crash also occurs with the following two UPSs: Cyberpower EC750G Tripp-Lite OmniSmart1500LCDT As before, to reproduce it.... 1) fresh install of OpenBSD current 2) do the reboot after the install 3) plug in the UPS 4) unplug it I can supply images of the crash screens for the two UPSs above if they are needed. Thanks!
