I have a problem with installing and running redhat7.5 on ibm x3850 x5 node 1 and node 2: when the kernel is loaded, the server restarts and no errors, no warnings in the log. Sometimes the system boots correctly, I don't understand why.
The system turns on more often if in the grub config write men = 1024M nr_cpus = 2 .
VMware is OK, Ubuntu is working properly, and CentOS and redhat are not ... please help me :)
