This is probably the same issue I'm experiencing: same error message, same workaround. Booting without quiet also results in a clocksource unstable message. I encountered it with a Sapphire PURE CrossfireX 770 equipped with an nvidia 8600.
the root cause could be this (taken from dmesg output): [ 21.816031] ACPI: I/O resource piix4_smbus [0xb00-0xb07] conflicts with ACPI region SOR2 [0xb00-0xb0f] device 0000:00:14.0 for me identifies the ATI SMBus. I'm suspecting a BIOS bug. -- Impossible restart after updating Ubuntu 7.04 to 7.10 https://bugs.launchpad.net/bugs/178896 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
