Rupert, You would not have to complain if you hadn't spammed your puny pretences. The boards and processors have issues to be known, accompanying warnings. The dmesg you posted does not help anything. It looks like a poorly done commercial for other operating systems that "supposedly" work. Only, you have not been running anything past boot up. Accept it, you are a troll. Looks like you point out there are "drivers to be written", for your use. I call this helpless whining. I told you how you can help this process.. Get the boards in the hands of developers with OpenBSD who write drivers. And first kindly ask about it whether it is possible to fit in busy work.

DUID changed?
So, today I was installing recent patches on my firewall box (a Dell R210-II) using openup/syspatch. After the reboot, it complained that it couldn't find [DUID].b for swap. After some panic, reboots, powercycles, etc. I realized that the DUID in fstab didn't match the DUID that was being used for /. I updated fstab to match, and everything is back to normal. Does anyone know how I might have done this, or how I can prevent it? BTW thanks for /bsd.booted. That made it easy to figure out the patch wasn't to blame. disklabel.sd0.backup: # /dev/rsd0c: type: SCSI disk: SCSI disk label: ST1000NM0011 duid: a0debfbdc4b3991a flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 121601 total sectors: 1953525168 boundstart: 64 boundend: 1953520065 drivedata: 0 16 partitions: #size offset fstype [fsize bsize cpg] a: 2097152 64 4.2BSD 2048 16384 1 # / b: 17206720 2097216swap# none c: 19535251680 unused d: 8388608 19303936 4.2BSD 2048 16384 1 # /tmp e: 41753472 27692544 4.2BSD 2048 16384 1 # /var f: 4194304 69446016 4.2BSD 2048 16384 1 # /usr g: 2097152 73640320 4.2BSD 2048 16384 1 # /usr/X11R6 h: 20971520 75737472 4.2BSD 2048 16384 1 # /usr/local i: 4195264 96708992 4.2BSD 2048 16384 1 # /usr/src j: 41929632100904256 4.2BSD 2048 16384 1 # /home k: 41929664142833888 4.2BSD 2048 16384 1 # /usr/ports l: 4192960184763552 4.2BSD 2048 16384 1 # /usr/obj m:150994944188956512 4.2BSD 2048 16384 1 # /home/squidcache disklabel.sd0.current: # /dev/rsd0c: type: SCSI disk: SCSI disk label: ST1000NM0011 duid: 5b645952b882641e flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 121601 total sectors: 1953525168 boundstart: 64 boundend: 1953520065 drivedata: 0 16 partitions: #size offset fstype [fsize bsize cpg] a: 2097152 64 4.2BSD 2048 16384 1 b: 17206720 2097216swap c: 19535251680 unused d: 8388608 19303936 4.2BSD 2048 16384 1 e: 41753472 27692544 4.2BSD 2048 16384 1 f: 4194304 69446016 4.2BSD 2048 16384 1 g: 2097152 73640320 4.2BSD 2048 16384 1 h: 20971520 75737472 4.2BSD 2048 16384 1 i: 4195264 96708992 4.2BSD 2048 16384 1 j: 41929632100904256 4.2BSD 2048 16384 1 k: 41929664142833888 4.2BSD 2048 16384 1 l: 4192960184763552 4.2BSD 2048 16384 1 m:150994944188956512 4.2BSD 2048 16384 1 (Where are the mount points?

Re: SuperMicro A2SDi-4C-HLN4F
I am not complaining about obsd. I am complaining about your FUD on C3000 and your request for a post-installation dmesg. No installation is possible for lack of disk drivers. I do not develop/port drivers. The dmesgs I already posted are all I can share. The only way to run obsd at this time is via qemu/proxmox or vmware/esxi.

Sat, 18 Aug 2018 08:29:33 + Rupert Gallagher > Orher architectures are explicitly known for being bugged, but this > did not stop the developers. Hi Rupert, Enough already, just post a full dmesg when you can. The hardware is not perfect, watch out for unfixed CPU bugs as these are soldered down chips. They also include a lot more than the CPU where most of the problems are. So keep an eye on these boards and be a bit more impartial and objective. It would be so nice if you could ship new boards like these to developers or donate some of your excess hardware costs so that they get the boards. That might be much more helpful than complaints over the installer dmesg.

I can pay you with your same currency. You have no experience installing openbsd on a new architecture: > Available disks are: none Your references are not specific to the C3000 architecture. Orher architectures are explicitly known for being bugged, but this did not stop the developers.
