The loader runs correctly, but incredibly slowly. It takes about 2 hours to get to the point where it enumerates the BIOS disks, although when it gets to that point, it does not take a long time to enumerate each disk. It takes about 2 minutes for each character change of the spinner! Fully completing the loader takes somewhere between 2 and 8 hours (I got bored watching it), and works correctly. The loader from the memstick image works normally. Daichi GOTO experienced something similar back in January [1], but there didn't seem to be any resolution to that problem. Disabling AHCI has no effect. Interestingly, we both have P45 based motherboards. I will try installing 8.0-RC2 tonight, and try to save verbose boot logs, dmidecode etc. If there is any other information I should be looking at, please let me know.
