I'm still getting this KSE panic. I'd like it to be added to 5.2's TODO
list.
I haven't tested the system without ACPI. First, as I say, because the
panic is difficult to reproduce. Second, because it didn't happen three
months ago, so it's unlikely to be a bug in my computer's ACPI, but a
bug in code. Therefore, it should be fixed, not masked.
This time I don't have a full backtrace because I had just compiled a
new kernel. Anyone knows how do I get kernel.debug installed right along
all the rest of the stuff? :-(
I don't know what the computer was doing, exactly, at the time. I was
running a full system upgrade. I believe it was running portupgrade at
the time.
