Re: Sparc t5120 firmware problem
Hello! I have a Sun Sparc t5120 that cannot start ldomd after a firmware upgrade. It’s possible to start ldomd before I have divided the machine into several guest domains. Afterwards it just hangs when trying to start ldomd and the machine is unresponsive (answers on ping though). Ldomd does not give any error messages. I've got almost the same hardware as you but I show a slightly newer version of the sysfw: Properties: ... hypervisor_version = Hypervisor 1.10.7.g 2014/07/10 11:46 macaddress = 00:21:28:16:2d:a8 maxbootfail = 3 obp_version = OpenBoot 4.33.6.f 2014/07/10 10:23 post_version = POST 4.33.6.f 2014/07/10 10:32 send_break_action = (Cannot show property) status = Solaris running sysfw_version = Sun System Firmware 7.4.8.a 2014/10/12 09:18 Getting older versions of the firmware without a support contract is a pain... But I'll try tomorrow for you. Do you know what version you where at before you upgraded? How old you want to try? I really appreciate your help! I was at version 7.2.7.d but I think it would be safe to go to version 7.2.11 which is the latest one in the 7.2 series. After that the hypervisor version goes from 1.7.x to 1.9.x (in firmware version 7.3.0). I don’t know if my problem is caused by a newer version of the hypervisor. Maybe one of the developers can answer which versions are supported by OpenBSD? Don't read too much into the fact that mine is working fine since I'm running slowaris on the cdom with OpenBSD-stable in ldoms so it's probably apples and oranges. The three OpenBSD ldoms I run are all working fabulously though (Thanks everyone that worked on the sun4v stuff). Up until now how has OpenBSD been doing for the primary? I'd love to ditch Solaris there too but I've got a large NAS hanging off this box and I rather like managing it with zfs.
Sparc t5120 firmware problem
Hello!
I have a Sun Sparc t5120 that cannot start ldomd after a firmware upgrade.
It’s possible to start ldomd before I have divided the machine into several
guest domains.
Afterwards it just hangs when trying to start ldomd and the machine is
unresponsive (answers on ping though).
Ldomd does not give any error messages.
Does anyone have any idea why?
Right now my plan is to downgrade the firmware. Does anyone have a known
working version to provide me?
I only have version 7.4.8 and nothing older.

Routerboard RB600 and hifn(4)
Hello! Does anyone on the list have experience with a hifn(4) card (such as the Soekris vpn1411) in a Routerboard RB600? I'm using it for an ipsec tunnel (isakmpd between RB600 and an other OpenBSD i386 box) and would like to know if it will give me any performance increase before I purchase one? Today I get about 12 Mb/s through the tunnel and 60-70 Mb/s outside. I am measuring this with iperf on OpenBSD 5.0 and the RB600 CPU is set to 533MHz. /Stefan
fmt_scaled, linking problem
Hello!
I am wondering if anyone else has seen this problem in the latest current \
snapshots.
I have a C-program that uses the fmt_scaled function from util.h.
This program compiled and linked fine a couple of weeks ago but now I get the
\
following error:
/tmp//ccUmAX34.o(.text+0x34): In function `main':
: undefined reference to `fmt_scaled'
collect2: ld returned 1 exit status
It will compile if I run `gcc -c` without linking.
Just to demonstrate i tried this little piece of code:
#include errno.h
#include stdio.h
#include util.h
int main(int argc, char *argv[]) {
char buf[FMT_SCALED_STRSIZE];
long long ninput = 10483892;
if (fmt_scaled(ninput, buf) == 0)
printf(%lld - %s\n, ninput, buf);
else
fprintf(stderr, fmt scaled failed (errno %d), errno);
}
Any hints would be very much appreciated.
Here is my dmesg:

I have tried looking in the log files for some explanation but I haven't found any clue myself. Maybe someone here could guide me in the right direction or knows what happened based on the attached dmesg and /var/log/messages simplified: It means the kernel run out of memory. When it is low on memory, the pagedaemon wakes up and tries to move pages to swap and other things. If in the process of doing that, the kernel really runs out of memory, it will start to wake itself up, basically looping around the pagedaemon to get some memory to free more memory... The message tells you that it detected this situation and hopes that one of your processes gives up and releases some. Usually however that doesn't happen ;) Update to 4.4+patches (not just release, there's an important fix you want...).
