kde shutdown freeze up
 

I just got my new sata2 drive to boot Mandriva-2006 & decided to use my old pata drive as a bootable backup drive. Everything works but the pata drive will not shutdown from the kDE start menu. It freezes up during the shutdown leaving me facing a solid blue screen & a big black "X". Also, the ctrl+alt+del key combination has no effect after the freezeup.

Now, if I type "shutdown -h now" or "shutdown -r now" in konsole as root (su) user the pata drive will shutdown properly.
The new sata2 drive has no problems shutting down.

Here is a copy of the relevent boot files. I would appreciate any suggestions. Thank you

Might be an ACPI problem. Have you any special settings in the BIOS?

Thank you for your reply.

I do have sata drives enabled in bios & I chose the ahci mode for sata operation so that I could take advantage of (NCQ) Native Command Querre & allow the sata2 drive to opperate at 3.0Gbs vs 1.5Gbs.

Also,by selecting ahci sata mode, a new bios option shows up asking me to enable or disable "Serial ATA BootROM". The asus bios manual says that this option appears only when the SATA controller is set to RAID or AHCI.

I am not sure what Serial ATA BootROM is but, since I want my sata drive to be bootable, I chose to "enable it.:scratch:

Sounds sensible but is not what I meant. ACPI is the feature(s) which allow a computer to "sleep" e.g. suspend to RAM but also suspend to disk. That is why I asked for those settings ... ?
