Comment (by hunnia1):
Interesting!
As I wrote disabling SMP will make AHCI/Haiku almost work except it will
not see sda.
So I went into debug mode with screen output and SMP disabled, to get some
photos. At the end of the sequence sda was seen.
Booted from the hard drive (sda) with smp disable, screen output and
automatic paging.
Haiku booted from the hard drive and worked perfectly.
Tried it again witout the screen output and it failed. (Could not find
root file system, which is obvious since sda not found.) Went back to
screen logging and it worked again.
Obviously there is something timing related. Race condition?
