ACPIHED(4)                   Device Drivers Manual                  ACPIHED(4)

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.
