Len, please consider my Lenovo T60 laptop "possibly affected" too. I
was seeing weird sporadic reboot hangs which went away roughly since
around that revert.
So the negative scope of the change, even after such short amount of
testing, is non-trivial, and we simply have to go via a flag day date
approach. Or, if these bugs are debuggable, make the ACPI reboot
sequence more reliable.
Ingo
