Grub-efi in combination with "reboot=a,w" fixed the kernel crash issue on reboot for an AMI-based BIOS (dated April of this year, will provide more details soon) for an Athlon II X2 245e-based system both for kernel version 2.6.38 and 3.0.0. Halting the system with either shutdown -P or -H still crashes the kernel, pm-hibernate works though.
