Hello All I thought I would just give you an update and solution to a problem I was having with the above. Basically the machine would show no hard disks when AHCI driver was loaded, with the following showing up at boot. ahcich0: Poll timeout on slot 0 (aprobe0:ahcich0:0:0:0): SIGNATURE: 0000 ahcich1: Poll timeout on slot 0 (aprobe1:ahcich1:0:0:0): SIGNATURE: 0000 ahcich2: Poll timeout on slot 0 (aprobe2:ahcich2:0:0:0): SIGNATURE: 0000 ahcich3: Poll timeout on slot 0 (aprobe3:ahcich3:0:0:0): SIGNATURE: 0000 ahcich4: Poll timeout on slot 0 (aprobe4:ahcich4:0:0:0): SIGNATURE: 0000 ahcich5: Poll timeout on slot 0 (aprobe5:ahcich5:0:0:0): SIGNATURE: 0000 ahcich0: Timeout on slot 0 ahcich1: Timeout on slot 0 ahcich2: Timeout on slot 0 ahcich3: Timeout on slot 0 ahcich4: Timeout on slot 0 ahcich5: Timeout on slot 0 run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config ahcich0: Timeout on slot 0 ahcich1: Timeout on slot 0 ahcich2: Timeout on slot 0 ahcich3: Timeout on slot 0 ahcich4: Timeout on slot 0 ahcich5: Timeout on slot 0 Someone suggested that the drives were not in AHCI mode, I was 99% sure that they were as it was the only way I could get all 6 sata ports working, but until today I had not had a chance to confirm this. The drives were already set to AHCI in the bios, and showed up in the AHCI bios util and also at post. I did some googling and it seems this is an issue with AMD SB700 chipsets as someone else had come across the same problem. I gave a snapshot of 9.0 a shot just to see if the problem existed in 9.0 as well as 8.0, it does. Last resort was to do a BIOS update of the mainboard, as it was on the original release F1 and F4 was available. On reboot I noticed the AHCI bios revision had changed 00078 from 00070, I still get a couple of timeout messages on boot, but the drives now detect and work just fine. Regards Graeme
