It does look like the IO isn't completing, suggesting an interrupt problem. Indeed, disabling the apic (set hint.apic.0.disabled=1 at the loader prompt) solves the tasting issue! But strangely enough, another Thinkpad X40 I tried did not need hint.apic.0.disabled=1 to boot from the same 8.1-REL install media. Hmm, I start to suspect hardware problems, or an old BIOS. Another issue with the problematic X40 is that it fails to mount the install DVD in fixit mode. So, lets close this PR - the problem seems to be due to faulty hardware. Bengt
