crash: seek error: kernel virtual address: ffff93e0876dbbc0 type: "current_task (per_cpu)" #147

Closed everschen closed 1 year ago

everschen commented 1 year ago

I have installed the latest crash image, but still got "crash: seek error: kernel virtual address" error, does it means I have to rebuild the kernel without "[] Randomize the address of the kernel image (KASLR)"? any comments are welcome, thanks.

WARNING: kernel version inconsistency between vmlinux and dumpfile

Is the vmlinux consistent with the kernel?

What is printed with "-d 8" option?

everschen commented 1 year ago

my env as below: evers@xiaomi:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04.6 LTS Release: 20.04 Codename: focal evers@xiaomi:~$ uname -a Linux xiaomi 5.4.0-153-generic #170-Ubuntu SMP Fri Jun 16 13:43:31 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

and I found the most match symbol from here: http://ddebs.ubuntu.com/pool/main/l/linux/linux-image-unsigned-5.4.0-152-generic-dbgsym_5.4.0-152.169_amd64.ddeb

I believe this is the reason why warning is there.

I will do kdump again, and get output with option "-d 8" later

k-hagio commented 1 year ago

Linux xiaomi 5.4.0-153-generic ...

linux-image-unsigned-5.4.0-152-generic-dbgsym_...

um, I'm not familiar with Ubuntu, but at least the dbgsym looks inconsistent with the kernel... The crash utility requires the exact vmlinux, "a close version" will not work.

everschen commented 1 year ago

I don't know why but it looks ubuntu 22.04 also has no exact version from that link [http://ddebs.ubuntu.com/pool/main/l/linux/], I guess it's same only the name different.
