It seems to be caused (or revealed) by the EC interrupt transaction patch. On the second suspend/resume cycle, I see a kernel error message. [ 78.747707] ACPI: Waking up from system sleep state S3 [ 79.330001] ACPI: EC: input buffer not empty, aborting transaction [ 79.423327] ACPI: EC: non-query interrupt received, switching to interrupt mode I still don't see any issues in the code. I'll try getting a DEBUG trace to see the EC interrupts. Any other suggestions? Thanks Alan
