Hmm, interesting. I assume the pauses had existed before I introduced the warning message (unexpected charge_types...), right? This sounds like a slow SMI handling due to the broken firmware. Could you kindly provide more detailed information about the pause? When it happened, did you notice a spike in CPU usage? Did you see any dmesg messag= e at that time? Did it freeze your system completely or just make things laggy? Could you also monitor the SMI count, i.e., sudo perf stat -e ls_smi_rx -I 1000 ..., wait for the pause to occur, and check how many SMIs have occurred dur= ing the pause? You can also mess around with sysfs attributes of ideapad-laptop, power_sup= ply, and firmware-attributes to see if reading them causes SMIs: sudo tail /sys/bus/acpi/devices/VPC2004\:00/physical_node/* sudo tail /sys/class/power_supply/*/* sudo tail /sys/class/firmware-attributes/*/attributes/*/* On my device, reading /sys/class/firmware-attributes/thinklmi/attributes/*/* always causes 580 SMIs, and other attributes do not cause any SMI. --=20 You may reply to this email to add a comment.
