On OpenBSD VMs running under Microsoft Hyper-V, I periodically see the following kernel message displayed on the console:
acpi0: PM1 stuck (en 0x101 st 0x1), clearing Looking at logs, it affects all OpenBSD VMs on the host, sometimes at the same time -- but sometimes not at all. Sometimes, +/- 30 seconds from each other. More notably, it doesn't seem to affect anything. These are Gen 1 VMs that boot in BIOS mode. Digging around, this message seems common to Hyper-V users of OpenBSD. VMware doesn't seem to be affected. Any ideas on the root cause? Regards Lloyd
