Please open a bug report: https://bugzilla.kernel.org/enter_bug.cgi?product=ACPI and attach the output from acpidump and dmesg -s64000 from your acpi=off boot. If you can take a photo of the failed boot, or otherwise describe it in more detail, that would be helpful. See if any of these random options help it boot: acpi=ht (likely this will work) acpi=rsdt acpi=noirq pci=noacpi thanks, -Len Brown, Intel Open Source Technology Center
