 I'm not sure what changed, but the contents of the bug claims that on
 machines where it doesn't work, it doesn't work as far back as 1.6.  I'm
 going to try 3.1_STABLE on my AC200 and will report what I see.

 For GNATS benefit, here's the original comments I added, that somehow
 didn't get into the PR (either I sent to the wrong address or GNATS
 somehow ate my original attempts):
 
 I'm seeing this same issue on a "new" (to me) Netra T1 AC200.  A couple
 of interesting additions:
 
 1. aceride0 (the on-board IDE controller supporting the CD-ROM) is also
 complaining of lost-interrupt messages during the bus probe.  I presume
 this and the SCSI timeout are caused by some system-wide interrupt
 routing issue.
 
 2. The hardware is fine; OpenBSD 4.2 installed on it A-OK (I didn't have
 Solaris media and wanted to verify that all system components were happy
 before my eBay non-DOA warranty ran out ;)).
 
 This was with a INSTALL kernel from a 2007-11-23 HEAD snapshot:
