Another user on misc@ confirmed this, so I am submitting it to bug@.
Please let me know if I need to do anything else. Many thanks! Mike. I run NUT on OpenBSD to monitor a Cyperpower UPS. The UPS plugs into the OpenBSD box via a USB connection. OpenBSD 6.8, I had no problems, everything ran fine. When the power went out, NUT saw that and reacted according to configuration. After I upgraded to OpenBSD 6.9 (a fresh install, not an in-place upgrade), when the power dropped, I'd be greeted with a blue crash screen. It seems that when the power drops, the UPS temporarily drops the USB connection, seemingly the equivalent of unplugging the USB connector. I am able to reproduce that 100% by booting up OpenBSD 6.9 with the UPS communications cable plugged into the USB port. When I unplugged that USB connector, the crash occurs. This first occurred on my production box which is a Supermicro motherboard. I can provide that dmesg if needed. Both OpenBSD 6.8 and current below are fresh installs on a test Lenovo laptop. On OpenBSD 6.8, when I plug in the UPS and unplug it, here is what I see on the console (dmesg is included): vvv========= OpenBSD 6.8 ====================== OpenBSD 6.8 (GENERIC.MP) #3: Sat Jun 5 10:34:16 MDT 2021 t...@syspatch-68-amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 4129800192 (3938MB) avail mem = 3989590016 (3804MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.6 @ 0xe0010 (78 entries) bios0: vendor LENOVO version "6IET75WW (1.35 )" date 02/01/2011 bios0: LENOVO 2522DU5 acpi0 at bios0: ACPI 4.0 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT ECDT APIC MCFG HPET ASF!
