ACPIHED(4)              NetBSD Kernel Interfaces 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.
