I have a upgraded a server with more than 1 TB of RAM, and it is unable to boot. With 768GB of RAM all is working fine.
I got the following message :
Trying to allocate 1005 pages for VMLINUZ.
[Linux-EFI, setup=0x112a, size=0x3ecab0]
no free pages available
Error 27: Unrecognized command
I must have missed a simple command switch, but unable to find it.
cat /usr/src/linux/.config | grep HIGHMEM
along with auname -a
