Public bug reported: No problems with 2.6.17-7-generic kernel at all.
Upgrading to 2.6.17-10-generic produces a large cascade of errors that appear to be caused by failing ACPI support. The relevant dmesg lines: ---- powernow-k8: Found 2 AMD Athlon 64 / Opteron processors (version 1.60.2) ACPI: Invalid package argument ACPI Exception (acpi-processor-0275): AE_BAD_PARAMETER, Invalid _PSS data [20060707] powernow-k8: 0 : fid 0x0 (800MHz), vid 0x16 (1000 mV) ---- Probable symptoms include hanging on shutdown, HAL hanging during startup (does not respond to any signals; GNOME crashes on startup claiming HAL not initialized) If it's any help I have a Turion MT32 processor. ** Affects: linux-source-2.6.17 (Ubuntu) Importance: Undecided Status: Unconfirmed -- Regression: ACPI broken on Asus A6Km (AMD64) https://launchpad.net/bugs/63532 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
