[Bug 36158] Re: System does not power off on shutdown

[capacman]

After  Sitsofe Wheeler post on buggy bios issue, i upgraded my bios from revision 1006.1 to 1007.3(beta bios). But the problem remains same. However upgrade i made some tests. First, i turned off acpi 2.0 support from bios. This did not change anything. But when i turned off acpi apic support , it said some weird things in boot process. Those are:
acpi: acpi bus type scsi registered
#set misaliggned resource pointer: df861dc2 type 07 len 0
ata1 slow to respond
after those warnings my harddisk worked slowly. Actually i do not know whether this information is related to this bug but i reported it because it hapened after i turned off acpi apic support. Then i turned on acpi apic support. But i encountered more interesthing thing accidentally. If i do not log into system when kdm asks me for my password and press ctrl+alt+f1 and then log in and issue the command sudo shutdown -h now, system shutdown properly. But if i log into system from kdm and issue the same command from ttys0 or from konsole or from start menu "turn off the computer" button after kde started it does not shutdown itself. is someone have an idea about that?(:))
