Comment 22 for bug 178896

Fabio, I have the same problem with an AMD 770 chipset (Biostar TA770SE motherboard). I experience random freezes, which I thought was due to my videocard having a bad V_BIOS checksum. My videocard is an ATI X300SE using the open-source radeon driver. I actually have a replacement (ATI 4550) being shipped to me this week.

I am getting this in my system messages on Ubuntu64 8.10, Ubuntu64 9.04, and Arch Linux64 using 2.6.28 kernel:
 ACPI: I/O resource piix4_smbus [0xb00-0xb07] conflicts with ACPI region SOR1 [0xb00-0xb0f]

I wonder if this is an inherent problem with this chipset (poor HPET support)?

Fabio, you said - "Booting without quiet also results in a clocksource unstable message."
If it's clocksource_tsc (the processor's clock), this is expected behavior because of power-saving schemes (PowerNow, Cool'n'Quiet,Speedstep)

I will keep testing, playing with using the jiffies clock sources and such and get back to you on this bug.
