Subject: arm64/acpi: Add fixup for HPE m400 quirks
|
||
|
|
Forwarded: https://lore.kernel.org/all/51d3d738-cdf5-2992-bba5-c3e1f34096c2@infradead.org/
|
||
|
|
|
||
|
|
Adds a new ACPI init routine acpi_fixup_m400_quirks that adds
|
||
|
|
a work-around for HPE ProLiant m400 APEI firmware problems.
|
||
|
|
|
||
|
|
The work-around disables APEI when CONFIG_ACPI_APEI is set and
|
||
|
|
m400 firmware is detected. Without this fixup m400 systems
|
||
|
|
experience errors like these on startup:
|
||
|
|
|
||
|
|
[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 2
|
||
|
|
[Hardware Error]: event severity: fatal
|
||
|
|
[Hardware Error]: Error 0, type: fatal
|
||
|
|
[Hardware Error]: section_type: memory error
|
||
|
|
[Hardware Error]: error_status: 0x0000000000001300
|
||
|
|
[Hardware Error]: error_type: 10, invalid address
|
||
|
|
Kernel panic - not syncing: Fatal hardware error!
