I tested the kernel-6.8 on my machine and found that the crashkernel memory reservation range is consistent with kernel-5.10. However, it's strange that when crashkernel=512M, the kernel still allocates two memory segments for crashkernel, as seen in the logs: [0.022640] crashkernel low memo

Thank you for your reply! The kernel version on my machine is kernel-5.10, and the kexec-tools version is kexec-tools-2.0.27. However, my issue seems to be a bit different. On my machine, I can see the crashkernel memory segment in /proc/iomem. However, for some reason, within the address range

Question about Address Range Validation in Crash Kernel Allocation

Dear kexec Community Members, I encountered an issue while using kexec-tools on my x86_64 machine. When there is a segment marked as 'reserved' within the memory range allocated for the crash kernel in /proc/iomem,the output appears as follows: 2d4fd058-60efefff : System RAM 2d4fd058-58ff :
