[1.] One line summary of the problem: Interrupt storm after plugin a device into one of the USB3 after resume on a Samsung NP550P5C laptop. [2.] Full description of the problem/report: After I resume the system and plug something in one of the machine's USB3 ports (it doesn't happen if I plug the same device on a USB2 port), the CPU load raises to 50%, with one particular process with the highest load: 4 root 20 0 0 0 0 R 50.1 0.0 1:43.63 kworker/0:0 The problem seems to be caused by too many ACPI interrupts: root@ubuntu:~# grep -r . /sys/firmware/acpi/interrupts/ /sys/firmware/acpi/interrupts/sci:12554973 /sys/firmware/acpi/interrupts/error: 0 /sys/firmware/acpi/interrupts/gpe00: 0 invalid /sys/firmware/acpi/interrupts/gpe01: 0 invalid /sys/firmware/acpi/interrupts/gpe02: 0 enabled /sys/firmware/acpi/interrupts/gpe03: 0 disabled /sys/firmware/acpi/interrupts/gpe04: 0 disabled /sys/firmware/acpi/interrupts/gpe05: 0 disabled /sys/firmware/acpi/interrupts/gpe06: 0 enabled /sys/firmware/acpi/interrupts/gpe07: 0 invalid /sys/firmware/acpi/interrupts/gpe08: 0 invalid /sys/firmware/acpi/interrupts/gpe09: 0 disabled /sys/firmware/acpi/interrupts/gpe10: 0 invalid /sys/firmware/acpi/interrupts/gpe11: 0 invalid /sys/firmware/acpi/interrupts/gpe12: 0 invalid /sys/firmware/acpi/interrupts/gpe13: 0 invalid /sys/firmware/acpi/interrupts/gpe14: 0 invalid /sys/firmware/acpi/interrupts/gpe15: 0 invalid /sys/firmware/acpi/interrupts/gpe16: 0 invalid /sys/firmware/acpi/interrupts/gpe0A: 0 invalid /sys/firmware/acpi/interrupts/gpe17: 1504 enabled /sys/firmware/acpi/interrupts/gpe0B: 0 disabled /sys/firmware/acpi/interrupts/gpe18: 0 invalid /sys/firmware/acpi/interrupts/gpe0C: 0 disabled /sys/firmware/acpi/interrupts/gpe19: 0 invalid /sys/firmware/acpi/interrupts/gpe0D:12553562 enabled /sys/firmware/acpi/interrupts/gpe0E: 0 disabled /sys/firmware/acpi/interrupts/gpe20: 0 disabled /sys/firmware/acpi/interrupts/gpe0F: 0 invalid /sys/firmware/acpi/interrupts/gpe21: 0 invalid /sys/firmware/acpi/interrupts/gpe22: 0 invalid /sys/firmware/acpi/interrupts/gpe23: 0 invalid /sys/firmware/acpi/interrupts/gpe24: 0 invalid /sys/firmware/acpi/interrupts/gpe25: 0 disabled /sys/firmware/acpi/interrupts/gpe26: 0 invalid /sys/firmware/acpi/interrupts/gpe1A: 0 invalid /sys/firmware/acpi/interrupts/gpe27: 0 invalid /sys/firmware/acpi/interrupts/gpe1B: 0 invalid /sys/firmware/acpi/interrupts/gpe28: 0 invalid /sys/firmware/acpi/interrupts/gpe1C: 0 invalid /sys/firmware/acpi/interrupts/gpe29: 0 invalid /sys/firmware/acpi/interrupts/gpe1D: 0 invalid /sys/firmware/acpi/interrupts/gpe1E: 0 enabled /sys/firmware/acpi/interrupts/gpe30: 0 invalid /sys/firmware/acpi/interrupts/gpe1F: 0 enabled /sys/firmware/acpi/interrupts/gpe31: 0 invalid /sys/firmware/acpi/interrupts/gpe32: 0 invalid /sys/firmware/acpi/interrupts/gpe33: 0 invalid /sys/firmware/acpi/interrupts/gpe34: 0 invalid /sys/firmware/acpi/interrupts/gpe35: 0 invalid /sys/firmware/acpi/interrupts/gpe36: 0 invalid /sys/firmware/acpi/interrupts/gpe2A: 0 invalid /sys/firmware/acpi/interrupts/gpe37: 0 invalid /sys/firmware/acpi/interrupts/gpe2B: 0 invalid /sys/firmware/acpi/interrupts/gpe38: 0 invalid /sys/firmware/acpi/interrupts/gpe2C: 0 invalid /sys/firmware/acpi/interrupts/gpe39: 0 invalid /sys/firmware/acpi/interrupts/gpe2D: 0 invalid /sys/firmware/acpi/interrupts/gpe2E: 0 invalid /sys/firmware/acpi/interrupts/gpe2F: 0 invalid /sys/firmware/acpi/interrupts/gpe3A: 0 invalid /sys/firmware/acpi/interrupts/gpe3B: 0 invalid /sys/firmware/acpi/interrupts/gpe3C: 0 invalid /sys/firmware/acpi/interrupts/gpe3D: 0 invalid /sys/firmware/acpi/interrupts/gpe3E: 0 invalid /sys/firmware/acpi/interrupts/gpe3F: 0 invalid /sys/firmware/acpi/interrupts/sci_not: 0 /sys/firmware/acpi/interrupts/ff_pmtimer: 0 invalid /sys/firmware/acpi/interrupts/ff_rt_clk: 0 disabled /sys/firmware/acpi/interrupts/gpe_all:12556159 /sys/firmware/acpi/interrupts/ff_gbl_lock: 0 disabled /sys/firmware/acpi/interrupts/ff_pwr_btn: 0 enabled /sys/firmware/acpi/interrupts/ff_slp_btn: 0 invalid I can mitigate the problem by disabling that particular source # echo disable > /sys/firmware/acpi/interrupts/gpe0D The issue was introduced in kernel 3.9 and has been present ever since.
