The system is a P4 3GHZ Hyperthreaded on a ASUS P4P800S-X board 1GB memory.  
  
After starting installation the last things that appear on comsole 1 are the   
following:   
   
Staring hardware detection ...   
Searching for info file ...   
   
Here the kernel print errors or hangs dending on irqpoll. Switching to console 
4 I can see lots of kernel   
messages of the following form:   
   
hdc: cdrom_pc_intr: The drive appears confused (ireason=0x01)   
irq 169: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #169   
   
This  log is from a boot with irqpoll=1. The installation continues in this  
case. Without irqpoll messages like above are repeated  several times and then  
the system hangs.  Disableing ACPI or hyperthreading did not help.  I also  
tried suse9.3. Here nothing helped the system hangs at the same point no  
matter what kernel parameters I tried (eg safe settings). Even irqpoll does  
not help out.
