When it prompts you 'Do you want to use all of wd0 for OpenBSD', just say yes, it will run fdisk -i It will make partition 3 the default active bootable one But I *never* want to use the entire disk for OpenBSD. I have a system for quick recovery in case of a disaster. I only use half of the disk. When I install a new version of OpenBSD, I use the other half of the disk. That way, if a disaster happens, I can quickly boot, run fdisk -- changing the bootable partition, and then reboot into my previous system. In the above fdisk output, partitions 0 and 2 are my current system, while partitions 1 and 3 are my last and next systems. After I install a new system onto partitions 1 and 3, partitions 0 and 2 will become my last and next systems. (Using 2 partitions like this is a holdover from the days when the bootable partition had to be in the first few cylinders of the drive.) From Absolute OpenBSD - UNIX for the practical paranoid by Michael Lucas I've learned that: OpenBSD partitions need to go within a single MBR partition. Dedicate a single MBR partition ... There can only be one OpenBSD MBR partition per hard disk. I can't make much sense of what you describe here, but to me it looks like it suggests that you're using a single disklabel which spans more than one MBR partition. Or even moving around the disklabel at will. If so, would you be willing to publish something like a howto on this subject?. Or else tell us where to find one? I know about multiple OpenBSD installations inside a single set of subpartitions, but that's still a single MBR partition. No fdisk or disklabel involved after initial setup, but probably more vulnerable than what you describe here. Bill I'm surprised more people don't do this. It provides for very quick and easy recovery in the case of a disaster. (I've only ever had such a disaster once; I've been using OpenBSD since late 1996.) The other advantage of this system is that it provides an easy means for seeing how I did things previously. I can quickly run disklabel, use an empty slice to point to one of my old slices, and then mount it. After I'm done I can run disklabel again and put it back. So I never want to use the entire disk for OpenBSD. Therefore, I will need to remember to escape to a shell and run fdisk -u when installing to a virgin disk. It would be nice if the OpenBSD install procedure checked for the lack of a valid MBR, and installed one automatically (after asking); that would save some people from experiencing the problem I experienced.

Anyway, after some more testing, I can finally start the X server without disabling radeondrm and without freezing the machine by adding Option BusType PCI to xorg.conf.

Booting with disable radeondrm in UKC and then running startx works fine. Doing the same with enable radeondrm (which is the default in the GENERIC kernel) appears to freeze the machine. The screen goes blank, and the monitor enters standby mode. Sometimes the computer shuts down after pressing the power button, but most of the time it can only be forced off by holding the power button. Trying several options in xorg.conf did not advance things. I booted with a serial console to see if any messages appeared after entering startx. This is what I got: radeondrm0: Setting GART location based on new memory map radeondrm0: writeback test failed radeondrm0: wait idle failed status : 0x80010140 0x radeondrm0: wait idle failed status : 0x80010140 0x radeondrm0: wait idle failed status : 0x80010140 0x ... The last message is repeated over and over until the machine appears to freeze. The time it takes to get to that point varies. After setting 'Option AGPFastWrite on' in xorg.conf no messages were output at all, but that was the only apparent difference. Setting AccelMethod to EXA also did not change anything. Using no xorg.conf at all also did not work. Anyway, here's my xorg.conf and dmesg. I hope someone can give me a hint.

But I reached a point where I had no choice but to get wireless working with these machines. I was amazed by how quickly I was able to do so (and that includes wap), in part because the documentation is so good. In general, the emphasis on quality of code and documentation in OpenBSD (as opposed to quantity, the hallmark of the bloatware that contaminates very nearly all of the world's computers today, and that includes those running certain Linux distributions), is something much appreciated by this user. I've tried almost all of them (Windows, multiple Linux distributions since Slackware in 1993, FreeBSD) and I don't believe there is anything available today as good as OpenBSD overall. /Don Allen -- Best Regards Edd Barrett

Or are you just worried about the numbers? B Search the archives for high load ... just for the record, i have seen a server where its typical load floats around 0.10 or so, but then something will happen and the plateau will get bumped to 1.10 and remain there. this was an 4.5 system. I have not identified what event caused this. I've seen similar issue with a couple of linux boxes at work where the load avg plateau will keep rising: it'll hover around ~3, then say ~6 then ~13. i don't think the issues are related, but could be caused by similar bugs in kernel. All systems continue to be responsive and it only seems that the reported load avg value is just bumped by a base value. It is definitely odd. Load on linux and load on BSD are two completely different things. On linux I recall load being the number of processes running or blocking, or something based on that. I know this is an old thread, but I came across this and thought I'd affirm this: from http://en.wikipedia.org/wiki/Load_(computing) -- Most UNIX systems count only processes in the running (on CPU) or runnable (waiting for CPU) states. However, Linux also includes processes in uninterruptible sleep states (usually waiting for disk activity), which can lead to markedly different results if many processes are blocked in I/O due to a busy or stalled I/O system. This, for example, includes processes that are blocked due to an NFS server failure or slow media (e.g., USB 1.x storage devices), leading to an elevated load average, which does not reflect an actual increase in CPU use (but still gives an idea on how long you have to wait). - In other words, ditto. I've always noticed (and then ignored) a difference between BSD/Solaris load average running the same processes vs Linux on the same hw. systat is much more useful, IMNSHO. -tico On BSD, load is the number of processes which have (wanted to) run at least once in the most recent 5-second window, with a degradation over time. So, if you have a process that wakes up every 5 seconds and prints the time on your console, you have a load average of 1. Load is not the number of cpu cycles used. A high load is just that: high. It means you have a lot of processes that sometimes run. High load does not mean your performance is going down or whatever: I ran a test today which generated a load of 200, but only used 10% of the cpu and was very responsive. You can't compare load on linux with load on bsd, I'd really appreciate if people stopped comparing apples and oranges. :P If you are interested in the internals of the system: load is the black magic that keeps the scheduling fair compared to the number of processes.

Okay, now in the freshly installed OpenBSD (guest):

And when I ping host's tap0 from it (default gw)
# ping 192.168.3.1

Because
# arp -an
? (192.168.3.1) at (incomplete) on pcn0
So I launched tcpdump to see what's wrong (on linux host):
$ sudo tcpdump -i tap0 -s 0 -w obsd1.dump
Booted OpenBSD, made few pings, halted it, then analyzed the dump:
$ tcpdump -t -r obsd1.dump
