# NAME

`acpihed` — ACPI Hardware Error Device

# SYNOPSIS

`acpihed* at acpi?`

# DESCRIPTION

Certain hardware error sources that can be queried by apei(4) notify an ACPI node with PNP ID ‘`PNP0C33`’ when an error occurs. The `acpihed` driver listens for these notifications and passes them on to apei(4) so it can report the error.
