With acpi=off, as expected there is no suspend function, battery meter etc. Shutdown appears to hang. The wireless card does not work (but that stopped working with the Xenial upgrade). Otherwise the system seems fine.
I am unable to find any other combination of acpi related boot options that work, apart from acpi=off. acpi=ht does not boot, which according to DebuggingACPI disables everything except hyper threading and "the issue is in the ACPI table parsing code itself, or perhaps the SMP code". I'll attach the documentation suggested in DebuggingACPI and the firmware test suite results. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1434136 Title: HP Pavilion 13-b208tu fails to boot Status in linux package in Ubuntu: Incomplete Bug description: When I updated to a version higher than F.23 but less than F.35, the computer wouldn't boot at all.
