** Attachment added: "dmesg"
https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.8/+bug/2066233/+attachment/5780750/+files/comment-3.txt
** Description changed:
Newer VBIOS on DCN 3.5 bumped the version of IntegratedInfo table from
2.2 to 2.3. This version uses same structure. Version 2.3 is missing
from the construct_integrated_info() parser, so it leads to NULL pointer
dereference.
