Below I appended the current dmesg of the patched sp kernel (by "patched" I
mean the patch by Marc from 9th of Februrary).
Also I played around with iasl to dissamble and reassemble the ACPI tables.
I came across the following issues:
* The disassembly of acpi.AAFT.7 contains the message "Unknown ACPI table
type [AAFT]".
* The disassembly of acpi.DSDT.2 contains the following line :
External (_SB_.PCI0.SBRG.TPM_.PTS_, MethodObj)
// Warning: Unresolved method, guessing 1 arguments
Using the -e switch I included all three SSDT tables when creating this
dissambly.
* The disassembly of acpi.FPDT.4 contains this error message:
**** ACPI table terminates in the middle of a data structure!
I don't know how severe these issues are. Is it possible that they lead to
the interrupt problem?
iasl does not complain about the problems in the acpi.APIC.3 table. So I
there could well be more problems with the tables going through unnoticed.
This is the dmesg:
