Hello,
Please can anyone help with the problem below when trying to install CentOS 7.6 on an IBM x3500 M3 from DVD or USB.
CentOS 7.5 installs perfectly with no errors.
CentOS 7.6 tries to boot, an error is output briefly and the workstation powers down.
CentOS 7.7 displays the error briefly then continues the install with no further errors.
I also tried RHEL 7.6 which installs perfectly with no errors.
Any ideas?
Wild guess : node is configured for UEFI and not legacy, *but* not with secureboot enabled ?
See https://bugs.centos.org/view.php?id=15522 if that matches with what you have.
Bug closed as it was fixed with a newer shim pkg, that is also the one used in 7.7 and it doesn't make sense to still deploy 7.6 while you also confirm that it works fine with 7.7 :)
