rhel7: fencing via IPMI does not work, only results in "kernel:Uhhuh. NMI received for unknown reason 3d on CPU 0."
Issue
When fencing with fence_ipmilan -i <BMC-IPaddr> -l <login> -p <pass> -o diag or directly with ipmitools then the target host does not reboot but instead only logs this:
Message from syslogd@host at Jun 18 16:44:06 ...
kernel:Uhhuh. NMI received for unknown reason 3d on CPU 0.
Message from syslogd@host at Jun 18 16:44:06 ...
kernel:Do you have a strange power saving mode enabled?
Message from syslogd@host at Jun 18 16:44:06 ...
kernel:Dazed and confused, but trying to continue
This worked until (including) RHEL7RC1, but after that not.
Environment
- Red Hat Enterprise Linux (RHEL) 7
