Thanks. I opened this bug report:
https://bugzilla.kernel.org/show_bug.cgi?id=54981 to keep track of
your logs.
Here's your _OSC method from the acpidump:
Method (_OSC, 4, Serialized) {
...
If (LAnd (LEqual (Arg0, GUID), NEXP))
... # normal case
Else {
Or (CDW1, 0x04, CDW1) # "unrecognized UUID" error
Return (Local0)
}
It fails with "unrecognized UUID" if either (1) we supply the wrong
UUID or (2) "NEXP" is false. I have no idea what NEXP is; your
DSDT.dsl never sets it, so maybe it's related to a BIOS setup option
or something? I found a BIOS manual [1] but didn't see anything
likely. I guess it might be worth you looking, or maybe trying a
"reset to defaults" if it's not too destructive for you. You don't
have a copy of Windows on that box, do you? I *assume* hotplug would
work fine with Windows and maybe we could figure out what it is doing
differently.
