ERST is the Error Record Serialization Table and is a MS defined ACPI table. From the kernel source tree:
Code:
driver/acpi/apei/erst.c
* APEI Error Record Serialization Table support
*
* ERST is a way provided by APEI to save and retrieve hardware error
* information to and from a persistent store.
*
* For more information about ERST, please refer to ACPI Specification
* version 4.0, section 17.4.
The error message is merely informational and may be caused either by the ACPI implementation on your machine or by the version of the kernel you're using.
On my Jurassic-era machine, I get:
Code:
ERST: Table is not found!
If the message bothers you, you can disable ERST support with the
erst_disable kernel command line parameter.
Hope it helps.
