Thanks for all the work everyone put into developing this, Vladimir in particular. The acpi=noirq work around is working here. I wanted to add, along with the scaling and the reboot fail issues, I also was not able to run ubiquity. The installer would crash giving me freedesktop.org errors.

The workaround makes networking very unstable (both WiFi and wired). 4.2.0-18 is OK. 4.2.0-19 is BROKEN. No suspicious configuration changes: $ diff /boot/config-4.2.0-18-generic /boot/config-4.2.0-19-generic 3c3 < # Linux/x86_64 4.2.0-18-generic Kernel Configuration --- > # Linux/x86_64

[Bug 1598312] Re: Cannot scale AMD Turion CPU frequency. It runs on lowest 800MHz

Vladimir, your solution works for me too. :) I have F.07 BIOS already. Setting acpi=noirq enables the possibilities to scale CPU processor frequency again on newest kernel on my notebook. However it is workaround not the final solution. It is nice to have well working kernel out of the box

[Bug 1598312] Re: Cannot scale AMD Turion CPU frequency. It runs on lowest 800MHz

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.

Same on HP Compaq nx6325 with AMD Turion(tm) 64 X2 Mobile Technology TL-52, including the fan running at full speed. But given the the thermal trip points, I think the CPU frequency scaling works as intended. When idle, with the old kernel I see $ uname -r 3.13.0-101-generic $ cat
