I'm trying and failing to get "memmap=8G$8G" passed to the kernel on its command line.
I have a vague ancient recollection of needing to do "memmap=8G\\\$8G, but it's not working now. I've tried lots of escape combinations but no luck. I've even put "memmap=8G!8G" in /etc/default/grub, run grub2-mkconfig, and then used hexedit on /boot/efi/EFI/fedora/grub.cfg to change the '!' to '$', but STILL the kernel sees the '!' Is this a bug or regression in grub2? I hope I'm just overlooking something obvious. Please help! $ rpm -qa | grep grub grubby-8.40-72.fc39.x86_64 grub2-common-2.06-109.fc39.noarch grub2-pc-modules-2.06-109.fc39.noarch grub2-tools-minimal-2.06-109.fc39.x86_64 grub2-tools-2.06-109.fc39.x86_64 grub2-pc-2.06-109.fc39.x86_64 Thank you, John Groves
