Can you look for messages about GPE / interrupt in the `dmesg` output? You might also able to use one or another kernel parameter from https://www.kernel.org/doc/Documentation/kernel-parameters.txt in an attempt to fix up the ACPI IRQs, try those that mention ACPI, IRQ and/or interrupt(s) in their name or description. Though; as this is a trial and error approach, a specific message and a better idea of what GPE 8 is might yield a better solution when searching this online. As a second question, to figure out what '8' is; take a look at `cat /proc/interrupts` where the last one or two columns of that line give it a name. Feel free to share both `dmesg` and that output with us. -- With kind regards, Tom Wijsman (TomWij) Gentoo Developer E-mail address : tom...@gentoo.org GPG Public Key : 6D34E57D GPG Fingerprint : C165 AF18 AB4C 400B C3D2 ABF0 95B2 1FCD 6D34 E57D
