Package: grub2 Version: 2.04-20 Severity: normal Dear Maintainer,
Hello! My old notebook has memory issues and requires to cut last 20M memory region to work propertly (no matter how much installed 1G or 2G I had to cut last 20M) >From kernel perspective it looks like this: [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000e0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000007f73ffff] usable [ 0.000000] BIOS-e820: [mem 0x000000007f740000-0x000000007f74ffff] ACPI data [ 0.000000] BIOS-e820: [mem 0x000000007f750000-0x000000007f7fffff] ACPI NVS [ 0.000000] e820: remove [mem 0x7e400000-0xfffffffffffffffe] usable [ 0.000000] Notice: NX (Execute Disable) protection missing in CPU!

Same affects grub2. If region in use grub2 takes 2 minutes to boot into kernel. I recorded youtube video: https://youtu.be/BlTii6QL5oY I know grub2 has a 'cutmem' command which is not working propertly. When I issue a: 'cutmem 0x7e40000 0x7f73ffff' grub2 reports no change in 'lsmmap' output, which is not correct! I tested 'cutmem' on my second notebook with efi loader, and cutmem affects 'lsmmap' output with 'BADRAM regions' printed out. fast logs: https://linux-hardware.org/?probe=59b41381ed slow logs: https://linux-hardware.org/?probe=28a5b48a05 'grub-legacy' works fine, no slow downs!
