Hi Will, This m400 HEST problem is blocking me from enabling APEI support in Debian [1], so I'd like to come to a conclusion on it. In summary from [2], Riku and Graeme mention they still have some m400 systems in use. Mark did some investigation and found the cause to be generated by the

2018-07-04 Thread Ard Biesheuvel
As noted by Ian, many DMI based quirks for x86 ACPI machines disable features that can also be disabled via the kernel command line. Similarly, a quirk is under discussion for a arm64 ACPI machine [0] that explodes when enabling support for hardware error reporting via the ACPI HEST table. When
