Hello Greg,
We need the following 2 upstream commits applied to 5.4.y to fix an iBFT boot failure:
2021-03-29 rafael.j.wysocki@intel.com - 1a1c130a 2021-03-23 Rafael J. Wysocki ACPI: tables: x86: Reserve memory occupied by ACPI tables 2021-04-13 rafael.j.wysocki@intel.com - 6998a88 2021-04-13 Rafael J. Wysocki ACPI: x86: Call acpi_boot_table_init() after acpi_table_upgrade()
Currently, only the first commit (1a1c130a) is destined for 5.10 & 5.11.
The 2nd commit (6998a88) is needed as well and both commits are needed in 5.4.y.
Is this a regression (i.e. did this hardware work on older kernels?), and if so, what commit caused the problem?
These commits are already in 5.10.y, what changed in older kernels to require this to be backported?
thanks,
greg k-h
