Hi,i bought a brand new ABIT AX78 motherboard (AM2+ AMD 770 / SB600) with the last bios (12) that supports the AMD 9750 Phenom X4 stepping 3. But it has some issues with ACPI. The information i can give you is not complete, the computer is about 200km far away from me as i'm writing this email. Anyway, i took some notes.
During early boot process, i can read something like that: "thermal ACPI: Expecting a [Reference] package element, found type 0" followed by:"ACPI Exception (thermal-0469): AE_ERROR, ACPI thermal trip point state changed"
with a message asking to send the file acpidump.txt to your list.The post code displayer reports nothing and deactivating the FANEQ feature in the bios does nothing either.
FYI, the bios lets me activate XSDT table for 64bits OS, what i have done, but this does not change anything.
Also, i had to set the kernel parameter pci=nommconf, otherwise the on-board Marvell Gigabit ethernet card is not always recognized even when the kernel module is forced loading. I'm using sky2 kernel driver. Probably not related but it could be relevant, the same appends sometimes with the ps2 keyboard. As a workaround i use the i8042.npnp parameter to make the keyboard work.
The 4 cores cpu overheats with the thermal module driver loaded, certainly because it is polling every 30s and it generates a lot of warnings.
The kernel used is: Linux 2.6.26-rc6 vanilla branch.Moreover, the motherboard has one interesting feature: it is able to power off via acpi if the cpu overheats but the notice does not inform how the OS can manage it.
I hope i give you a few helpful indications.
