>Description:
After reconfiguring an existing carp interface with the same ip the 
gateway stops forwarding traffic (forwarding to directly connected hosts still 
works).
In /var/log/messages this can be found:

Dell PowerEdge R710 boots with 6.0 but not 6.1

2017-07-10 Thread scott 

Synopsis:   Dell PowerEdge R710 boots with 6.0 but not 6.1
Category:   kernel
Environment:

System  : OpenBSD 6.0
Details : OpenBSD 6.0 (GENERIC.MP) #2319: Tue Jul 26 13:00:43 MDT 
2016
 
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

Architecture: OpenBSD.amd64
Machine : amd64

Description:


I have run OpenBSD 6.0-stable on my Dell PowerEdge R710 for several 
months without incident. Recently I attempted a fresh install of OpenBSD 
6.1 on the machine, and the installation itself seemed successful, but I 
can no longer boot...it gets as far as "savecore: no core dump" before 
it stops progressing, and about 5 minutes later, shows a message in 
white text on a blue background. I've experimented with different power 
management settings in the BIOS and I've tried updating all the blobs, 
neither improved the situation. Each time I boot I get a different 
message:


1st try


savecore: no core dump
NMI ... going to debugger
Stopped at  acpicpu_idle+0x22d: nop
ddb{1}> kernel: type -1735280128 trap, code=0
Faulted in DDB: continuing...
ddb{0}> kernel: type -1735280128 trap, code=0
Faulted in DDB: continuing...
ddb{0}>

2nd try


savecore: no core dump
NMI ... going to debugger
Stopped at  0xbf77dd006f3:  addq$0x1,%rdx
ddb{1}>

3rd try

This time a bunch of the screen was covered in blocks of color, some of 
which would cycle between different characters every second, always the 
same blocks staying the same and the same ones changing. I could only 
make out part of the message:


NMI
   ped at  cpu_idle+0x22d:   nop
   kernel:

I tried running sendbug as root, to capture the ACPI data, but on each 
of 2 attempts, the acpidump process would peg the CPU for 10 minutes or 
so before the machine would reboot.


I tried getting some more info out of DDB, but my keyboard wouldn't
work, maybe because its USB? I don't see a PS2 port on this machine so I
cannot try using a PS2 keyboard. It has a serial port, I tried
connecting to that using cu from a different machine, but I didn't see
any output.


How-To-Repeat:


Install OpenBSD 6.1 on a similarly configured Dell PowerEdge R710.
Reboot. Observe the issue--you cannot boot.


Fix:


Use the older OpenBSD 6.0-stable instead.
