Is that /proc/kcore? What is the kernel version?
Yes, the kernel version is 6.5.0-rc1.
Thanks, I found a 6.5 environment that could reproduce this.
crash> sys
KERNEL: /lib/modules/6.5.9/build/vmlinux
I only find v6.5-rc1 ~ v6.5-rc7 in Linus's tree.
What does the 6.5.9 mean?
I tested the stable tree with tag 6.5.9:
