Correct, "irqpoll /irqfixup" only allow the system to read the partition and
disk info prior to scsi0 : MESH init. Still results in hang at scsi0 : MESH
with subsequent hde/f/h: lost interrupt messages. Installed system has never
successfully completed boot with or without "irqpoll / irqfixup". 

It is curious though that Live CD and alternate CD both load and operate
without error (no hang or stall)...this is dmesg snip from Live CD:
