As I've mentioned in a previous thread, among the machines on which I'm running OpenBSD 4.5 is a Lenovo Thinkstation S10. 4 cores, 4 Gb memory, 2 146 Gb SAS disks on an LSI raid controller, arranged as a raid 0. Two questions: 1. In the past, running Linux, I've backed this machine up (to a sata drive in a usb shoebox) by booting a live- or install-cd, the idea being to have the system completely quiescent during the backup. I've been absolutely stymied in trying to do the same thing with OpenBSD. The install45 cd does not have enough sd* devices (the sd0 series only), so I can't mount both the raid 0 and the backup drive. The two live cds I tried (bsdanywhere and jggimi) both fail during booting, complaining they can't find their root filesystem. In order to get any flavor of OpenBSD to boot on this machine, I have to get into ukc and disable uhci. Thinking that might be causing this problem, I tried the jggimi livecd on my Thinkpad X61 (2 64-bit cores) both just letting it boot and doing the ukc->disable uhci sequence. In both cases, the system booted successfully (no problem finding the root file system on the ramdisk). Hopefully temporarily, I've worked around this problem on the workstation by booting the installed system and backing it up while it's running, shutting down some key things (e.g., postgresql). But I would like to solve this problem one way or another and be able to boot enough of a system from a cd to be able to run my backup script. 2. If I boot the install45 cd (bsd.rd) on the workstation (after disabling uhci in ukc) and run reboot from the shell, the system reboots normally. If I boot the installed kernel (bsd.mp) and run reboot from the shell, the system powers down briefly and then comes back up and reboots. OpenBSD does not behave this way on the two Thinkpads on which I have it installed. Nor have I seen this behavior with Linux or FreeBSD that I had run previously on the workstation. I did get into the bios setup at one point, to see if there ...
You can freely create additional devices: # cd /etc && sh MAKEDEV sd1 For the rest of your mail - it's not clear, did you tried -CURRENT? I remember there were some commits related to X38... -- Best wishes, Vadim Zhukov A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
I have not tried -CURRENT. I'll check the cvs logs to see if I can find anything that seems relevant.
I'll recommend you to try it anyway. If it'll help then you can find a fix in CVS; if it will not then developers may pay attention to your problem; they do not care much about something already fixed, unless it is considered critical. -- Best wishes, Vadim Zhukov A: Because it messes up the order in which people normally read text.

Why not use a single-user mode ( -s from boot prompt) for this? I am not the one able to help with this, but the dmesg output (/var/run/dmesg.boot) is almost always needed. Look at the section 'Reporting Bugs' in the FAQ first. Also, check with Lenovo if there are any bios updates available. Btw, do you experience the uhci troubles under OpenBSD/i386 (you forgot to mention here that you are running amd64)? Booting i386 bsd.rd should be enough to test. Maybe this comparison could be helpful. Regards, David
Good idea -- I'll try it.
