Have you tried boot -c disable inteldrm If it works, use config -ef /bsd to make it permanent. no, don't do that. that just stupidly hides the bug and pretty much makes sure it won't get fixed (unless someone else runs into it too and doesn't pick stupid workarounds). this however IS useful to (mostly) verify inteldrm itself is to blame. Thanks to Alexander and Henning for the suggestions. By disabling inteldrm at boot time, I was able to get one of the Supermicro mobos to boot OpenBSD 5.0. From that instance, I used sendbug(1) to mail a bug report. From looking at the changelog http://openbsd.org/plus48.html I see that two changes were checked in between 4.7 and 4.8 related to inteldrm. Hopefully this helps the maintainer of that module to track down and fix the problem. Happy New Year to All! Cheers, --Bill
inteldrm_attach still broken
Hi, Back in June of 2011, I reported problems with the Supermicro P8SCI and P8SCT motherboards failing to boot OpenBSD 4.8 and 4.9, due to a kernel page fault trap at interdrm_attach. Just for fun, I tried OpenBSD 5.0 tonight, and the same problem still happens. Has anyone found a workaround for this, or are there any plans to fix it? I have several of these motherboards running in firewalls, and unless I can find a fix, these boxes are trapped at OpenBSD 4.7 until I can replace them all. If anyone needs a box to test on, it looks like I'll have quite a few spares :-) Thanks, --Bill

Hi Daniel, I fondly remember the days when I had the time to do things like that. Unfortunately, these days, I'm just a luser who buys the OpenBSD CDs and makes networks run. Frankly, it's far less expensive for me to replace all of the SuperO P8xxx machines running OpenBSD than it is to spend time tracking down this kernel bug. I'll happily donate a machine to the project if any of the developers are interested in fixing this. Meanwhile, I'll be installing OpenBSD 5.0 on machines that it works on, so that I can move forward with what I need to get done. Cheers, --Bill
Re: OpenBSD current i386 hangs on boot in lm0.
On Wed, 6 Jul 2011 17:23:08 +0200 (CEST), Francois Pussault wrote Hi all, Medion computers, supermicro (many cheap models) motherboards are known as 'not free *unix* compatible'. Therefore most of supermicro other motherboards just seem to work well with *linux *BSD. Madion are hardware coded to be able only to boot a real windows OS, (even reactOS often fail to boot correctly), Then you need to boot other OS to have a windows installed in first partition(s) to use a multiboot, but even that can fail I have to disagree about Supermicro. I have been using their motherboards since the mid-2000s, and they are neither cheap nor unfriendly to free unices. The biggest problem is that their support people are generally not unix people. I never had any trouble running OpenBSD on their products until 4.8, when it started hanging on boot, which I reported to this list previously. ~~~

And maybe a read-through of http://www.openbsd.org/faq/faq5.html (this will probably answer the questions you are about to ask in response to the above...) Nick. Thanks for the response. Unfortunately, we don't have enough time, or spare machines, to compile from scratch and test, while still maintaining a few hot spares. So for now, we'll try to come up with more hardware, or in the worst case, wait for the next release (4.10)? Thanks Again, --Bill
