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? Regards, Mark Woolfson MW Consultancy Ltd Leeds LS18 4LY United Kingdom Tel: +44 113 259 1204 Mob: +44 786 065 2778
