Trying the different kernel parameters suggested at https://wiki.ubuntu.com/DebuggingACPI I've got these results:
acpi=off: kernel panic (something too do with PCI) acpi=ht: no change pci=noacpi: kernel panic (something too do with PCI) acpi=noirq: WORKS So this is a bug in ACPI IRQ routing. Recommended workaround is acpi=noirq. (Now how to configure grub to add that kernel parameter when doing update-grub?) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1598312 Title: Cannot scale AMD Turion CPU frequency.
