Subject : No power-off / reboot with 2.6.25-rcX (up to -rc3)
Interestingly, if I reboot -immediately- from gdm, it succeeds. However if I login to Fedora GNOME via gdm, and load my standard apps (1001 terminals, firefox, tbird, IRC) reboot and poweroff no longer work.
My guess was always some ACPI regression. I'll bisect today or tomorrow. It is reproducible regression that appeared recently (circa 2.6.24 or 2.6.25-rc1 I think), so I should be able to find the culprit.
