RHEL 7.4 LE for PPC64 hangs during installation

Latest response

Hi everyone. Trying to install RHEL 7.4 LE for PPC64 on an IBM Power 7 8205-E6D machine. I have 16 cores and 256 GB of memory. During installation I get to a certain point and it hangs (see below). I tried to install 7.3 LE and it does the same thing. I tried to install 7.3 BE and that seemed to work. Is there something wrong with my machine setup? Please advise. Thanks

Any sort of IBM Power architecture issues will most likely need a support case. Mostly because very very few people in the "community" have Power8 ( an upwards ) systems to compare with. However, having said all that, I wish I had a Power8 system becasue they are awesome and they are RISC which has always been better than CISC.

I happen to have a few dozen ppc64LE LPARs running on Power8 hardware running MongoDB :)

IBM info It looks like that particular hardware only supports Power BE,
