Maciej W. Rozycki reported: > 82093AA I/O APIC has its version set to 0x11 and it > does not support the EOI register. Similarly I/O APICs > integrated into the 82379AB south bridge and the 82374EB/SB > EISA component. IO-APIC versions below 0x20 don't support EOI register. Some of the Intel ICH Specs (ICH2 to ICH5) documents the io-apic version as 0x2. This is an error with documentation and these ICH chips use io-apic's of version 0x20 and indeed has a working EOI register for the io-apic. Fix the EOI register detection mechanism to check for version 0x20 and beyond. And also, a platform can potentially have io-apic's with different versions. Make the EOI register check per io-apic.
