>Synopsis: system freeze: acpicpu setperf failed to alter frequency
>Category: kernel
>Environment:
System : OpenBSD 5.7
Details : OpenBSD 5.7 (GENERIC) #0: Thu Apr 30 22:01:01 CEST 2015
r...@stable-57-amd64.mtier.org:/binpatchng/work-binpatch57-amd64/src/sys/arch/amd64/compile/GENERIC
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
After executing the command "sysctl hw" the server freezes without
dropping me to ddb. With OpenBSD 5.6 "sysctl hw" was working fine on this
hardware. It happens with 5.7 and -current mp kernels. sp kernels work as
expected.
Output from the serial console (with different kernel versions):

I have access to a similar server: HP ProLiant DL360 G5 with only one
quadcore cpu installed (Intel Xeon E5335). There this problem does not
appear.
>How-To-Repeat:
Install OpenBSD 5.7 amd64 on a HP ProLiant DL360 G5 with two
Intel Xeon E5440 cpus. Then do "sysctl hw".
>Workaround:
Run an sp kernel instead of mp.
