On A7V with BIOS 1012a01 2.5.40+ ACPI always worked flawlessly, while 2.4.x has problems. Currently (2.4.21-pre7) is better than before: it writes some panic to screen, but poweroffs immediately after that (and sorry, nearest serial console is about 5km far away, and everybody should use 2.5.x anyway), so I always suspected that problem is not in poweroff itself, but in some driver's devexit procedure (I have enabled hotplug in kernel, so __devexit is not stripped out).
And if you are talking about A7V, for some old ACPI (maybe all 2.4.x, I have no idea) take a look at http://groups.google.com/groups?q=vandrovec+acpi+poweroff&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=linux.kernel.20020124184011.GA23785%40vana.vc.cvut.cz&rnum=1 Best regards, Petr Vandrovec vandrove@vc.cvut.cz
