So it doesn't, and if you need to restart the computer that indicates a
problem with the ACPI support code, but I don't know if you have that
loaded at all.

So yeah, you were right when you said it's related to the BIOS, I just
thought you said reloading the module fixed it which I thought was very
strange. Since it doesn't, it's just the BIOS/whatever pulling the line
low and there's nothing the wifi driver can do about that, we can't even
ignore that.
