SubjectRE: [PATCH] ACPI suspend: Blacklist HP xw4600 Workstation for old code ordering
I don't know the technical details behind *how* Windows copes with it, but I can tell you that it works fine on Windows.  Naturally we'd like it to work fine on Linux, too, and Rafael's blacklist fix accomplishes that.  There may be other solutions to this issue on Linux that are worth looking into, but perhaps we can accept Rafael's fix as a workaround for now.

BTW, there is probably at least one more fairly recent vintage HP workstation that will require this same fix. My testing isn't complete yet, though.

So how does Windows cope with this?
