I am observing similar problems with HP Spectre x360 15-df0850nz. It does not boot without **acpi=noirq**. With *acpi=noirq*:
* Touchpad does not work * Touchscreen or pen does not work * Does not wake up after suspending * Keyboard sometimes does not work, but will be fine again after reboot Here is the dmesg log from kernel 4.18.0: https://alexandria.adynathos.net/d/2528a04f758c409c85c4/ I also tried kernel 4.20 from https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable but the problem persists. There are bugs filed on some of these topics, but they do not seem to cover the IRQ booting problem: * https://bugzilla.kernel.org/show_bug.cgi?id=201775 * https://bugzilla.kernel.org/show_bug.cgi?id=201885 I am new to ACPI errors, could you tell me how to proceed to best report or try to fix this?
