Description

On an older Pentium 4 Asus P4B266 machine (ICH2), something approximating bisection indicates that commit d83666e0134c4fe447b61f17ca7f22f4418b2d9b "Kernel - Completely remove DFLTPHYS" appears to result in boot failing with error messages such as:

ata0: FAILURE - oversized DMA transfer attempt 131072 > 65536
ad1: setting up DMA failed

Booting appears to be successful on newer Intel based machines using say ICH7 or ICH10 set hw.apic_io_enable=0 was already a requirement for booting on this ICH2 machine with post 2.10 kernels.
