Hi,
Unfortunately, I was not able to reboot in this kernel again to do the stack decode, but I thought
that any information about the NULL pointer dereference is better than no info.
The system is Ubuntu 23.10 Mantic with AMD product: Navi 23 [Radeon RX 6600/6600 XT/6600M]
graphic card.
Please find the config and the hw listing attached.
Best regards,
Mirsad

Hi,
The last email did not pass to the most of the recipients due to banned .xz attachment.
As the .config is too big to send inline or uncompressed either, I will omit it in this
attempt. In the meantime, I had some success in decoding the stack trace, but sadly not
complete.
I don't think this Oops is deterministic, but I am working on a reproducer.
The platform is Ubuntu 22.04 LTS.
Complete list of hardware and .config is available here:
