Hello Brian,

Perhaps a long-shot, but have you tried to apply:
https://lore.kernel.org/linux-pci/20260519-l1ss-fix-v2-0-b2c3a4bdeb15@xxxxxxxxxxxxxxxx/

to see if it helps your problem?


https://lore.kernel.org/linux-pci/r247uuc7ilkhn65vcbsaoxhgypif37lj3r3mvb7ooqqdg55vnm@vx3ip6klg6ha/
also seems to mention a recent PSCI fix:
https://lore.kernel.org/all/20251231162126.7728-1-manivannan.sadhasivam@xxxxxxxxxxxxxxxx/

Which also sounds somewhat related.


Kind regards,
Niklas
