from: drivers/acpi/apei/ghes.c (this is git head rather than any specific version):
if (hest_disable) { pr_info(GHES_PFX "HEST is not enabled!\n"); return -EINVAL; } then drivers/acpi/apei/hest.c: bool hest_disable; EXPORT_SYMBOL_GPL(hest_disable); static int __init setup_hest_disable(char *str) { hest_disable = 1; return 0; } and it's documented as a flag in ./Documentation/kernel-parameters.txt : hest_disable [ACPI] Disable Hardware Error Source Table (HEST) support; corresponding firmware-first mode error processing logic will be disabled. I can't actually see anything that sets hest_disable to anything other than 1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1091032 Title: [ 0.884475] GHES: HEST is not enabled!
