I encountered the same problem with upsteam linux-stable v6.5.4 and crash utility both version 8.0.3 and master branch.

I also tried

  1. long-maintained upstream kernel v6.1.55, which is ok with crash utility vesion 8.0.3.
  2. ubuntu 23.04's kernel6.2.16(custom build of official 6.2.0-33-generic), which will still report crash: page excluded: kernel virtual address: xxxxxxxxxxx type: "xa_node.slots[off]"

so there must be something changed in more recent kernels which break the crash utility

Hi muryliang, What is the version of makedumpfile that you're using to capture the vmcore?

I saw a similar message on Linux 6.2 once [1], upstream makedumpfile-1.7.3 and later support Linux 6.2. For Ubuntu makedumpfile, please consult Ubuntu community. [1] https://github.com/makedumpfile/makedumpfile/commit/5f17bdd2128998a3eeeb4521d136a192222fadb6

For Ubuntu makedumpfile, please consult Ubuntu community.

Probably this is it: https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/2038248 Please try.

Hi k-hagio, After upgrade to makedumpfile v1.7.3 from v1.7.2, both upstream kernel v6.5.4 and ubuntu's kernel v6.2 now can be sucessfully handled by crash v8.0.3. Thanks for your help.
