6.17.9 / 6.18 AMDGPU DMCUB Error

Hello all, please forgive me if this issue is already known, but I couldn't find any reference to it with regard to the 6.17.9 kernel.

Although an error is reported, the system still boots to the graphical interface and appears to function normally, although I have neither benchmarked graphics performance or used the system for an extended period after the error has been flagged. Yours faithfully, Neil Gammie

[PATCH] mm/readahead: read min folio constraints under invalidate lock

by Jinchao Wang

page_cache_ra_order() and page_cache_ra_unbounded() read mapping minimum folio constraints before taking the invalidate lock, allowing concurrent changes to violate page cache invariants.

Please drop from all queues, this depends on cbabc73e85be ("interconnect: qcom: qcs615: Drop IP0 interconnects") and has no visible effect today (the IP block this resource drives is not enabled), however potentially handling it in two places could cause issues Konrad
