This is exactly what many of us do, every day. So I'm not sure what's triggering your scenario. Any way to narrow it down more than "just use the system for a day or two"? Eg, "here's a script you can run inside an alpine VM that triggers the issue"? I'm guessing this isn't a vmd/vmm thing, as those components don't interact with acpi. We have seen stuck acpi threads on other machines after un-zzz/un-ZZZ in some cases. Were you doing suspends or hibernates? -ml > >Fix: > No idea. > > dmesg: > OpenBSD 7.6-current (GENERIC.MP) #407: Fri Nov 1 20:31:42 MDT 2024 >
