It can work for me with vmlinux with CONFIG_DEBUG_INFO_COMPRESSED_ZSTD set
Hope it could be good motivation to upgrade gdb as it seems to be more common to have it set

 

Thanks for pointing out this issue. Can you help to check if it can work well for you as below? Just want to confirm if crash also works well without the latest embedded gdb.

1. objcopy --decompress-debug-sections vmlinux

2. crash vmlinux vmcore

If yes, at least it can parse the current vmlinux(with compressed debug info) until the new gdb grade is completed.

Thanks

Thanks.
