>Description:
Machine is an IBM eServer xseries 330, dual 1.27 GHz P3 processors with 256 MB RAM.  Dual 9G SCSI drives with Adaptec controller.  This system has been running NetBSD 3.1 happily since it came out a year ago.  Now trying to install NetBSD 4.0 via CD burned from ISO.  Each attempt fails after SCSI controller (ahc1) reports several "lost interrupt" messages after "waiting 2 seconds for devices to settle."  The next thing that happens is a SCSI card state dump, with the controller going into and then coming out of reset.  I see the full dump info on the console, and of course after that the machine is effectively halted.  Sorry I don't have the exact console info as I have no way to capture it at this stage of the boot.  The MD5 of the ISO is correct and I burned several CD copies, but each has the same behavior.  It also should be noted that this problem is VERY SIMILAR to reports on earlier 4.0 betas that I found when browsing the web and PR database.  If fixes were supplied a
 t the time, perhaps they need to be looked at again.  The eServer diagnostics don't report any h/w errors for this system.  If I remove the 4.0 CD, I then reboot normally from hard drive 0 and NetBSD 3.1 runs as well as ever.
>How-To-Repeat:
Boot from a 4.0 install CD.
>Fix:
Haven't tried a floppy boot yet, or a PXE boot, but I don't recall that I had to go that route with 3.1 (or previous NetBSD's...  I have machines still running 1.6!!).  If this would be useful I can attempt it.
