Hi Josef, I'm still seeing it on with the latest ipmitool in 7.4:

[root@dell-pe1950-01 ~]# cat /etc/redhat-release

[root@dell-pe1950-01 ~]# rpm -q ipmitool

Hi Rachel,
is this reproducible anywhere? I saw that `dell-pe1950-01.lab.eng.rdu.redhat.com` was decommisioned.

Anyway, from what I got from the specs, event messages should be 7 bytes long for IPMB interface and 8 B for system interface, where 'Generator ID' is prepended.

Comment 9 Rachel Sibley 2019-11-07 20:48:41 UTC

Hi Vaclav, I haven't seen it since, I think we can probably close this in the case that I used an invalid message length

Comment 10 Vaclav Dolezal 2019-11-28 15:39:05 UTC

Well, ipmitools should autodetect that. I found commit upstream addressing similar issue (apparently there are some BMCs labeling their system interface as something else), but without machine to test it on, I'll close this bug.
