Synopsis: [geom] label tasting hangs during boot State-Changed-From-To: open->closed State-Changed-By: linimon State-Changed-When: Thu Aug 12 00:18:31 UTC 2010 State-Changed-Why: >From PR misfiled due to NFS glitch: Subject: Re: kern/149523: [geom] label tasting hangs during boot From: Bengt Ahlgren <bengta@sics.se> Date: Thu, 12 Aug 2010 01:06:10 +0200 I did some testing with wiping the first 100 sectors, but that did not make any difference. 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.
