The failure actually happened at the end of igt@gem_exec_suspend@basic-s3. I did not file the bug straight to kernel.org, because there is a chance this is a GEM-induced corruption.
The CI Bug Log issue associated to this bug has been updated. ### New filters associated * BSW: igt@runner@aborted - fail - Previous test: gem_exec_suspend (basic-s[34].*), Kernel badly tainted (0x60) - https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_5886/fi-bsw-kefka/igt@runner@aborted.html
I would say this looks pretty clear cut as a use-after-free of the skb.
