Hello. Intel produced a set of very nice mini-ITX boards with new Cedarview Atom CPUs onboard -- D2500CC, D2700MUD, D2800MT etc. Apparently all of these boards have issues powering off from linux. Here's the last few lines left on the screen when the system should turn the power off: ACPI: Preparing to enter system sleep state S5 ACPI Error (psargs-8359): [\_SB_.PCI0.LPCB.TPM_.PTS_] Namespace lookup failure, AE_NOT_FOUND ACPI Error (psparse-8537): Method parse/execution failed [\_PTS] (Node f703c504), AE_NOT_FOUND Disabling non-boot CPUs ... CPU1 is now offline SNP alternatives: switching to UP code Power down. _ The cursor is blinking, and power staus on. Is there anything can be done with this? Thanks! Besides, these boards have a bios bug which is kinda difficult to work around if you don't know how. Even with latest BIOS, the beasts don't REboot if the active partition is something not FAT/NTFS -- eg, any linux native filesystem. It boots fine after power on, but on reboot, instead of displaying bootloader prompt, the screen becomes blank with cursor blinking at the upper left corner, and after about 30..40 seconds staying in this state and not reacting to Ctrl+Alt+Del, the system reboots, ad infinitum. One can powercycle the motherboard and it will boot again (just once again), or it is possible to enter bios settings and save settings (without changing anything) -- this way it will also boot, but also just once. The workaround is to create a small fat16 /boot partition... Maybe this information will save quite some time and frustration to someone... ;) /mjt -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
