Hi I again encountered the same issue IRQ23 disabled. Here is my /proc/interrupts CPU0 CPU1 0: 381 0 IO-APIC-edge timer 1: 47 6499 IO-APIC-edge i8042 3: 2 0 IO-APIC-edge 4: 4 0 IO-APIC-edge 6: 7 0 IO-APIC-edge floppy 9: 0 0 IO-APIC-fasteoi acpi 12: 4 0 IO-APIC-edge i8042 14: 27742 0 IO-APIC-edge ide0 15: 3152 809663 IO-APIC-edge ide1 16: 383 0 IO-APIC-fasteoi uhci_hcd:usb2, uhci_hcd:usb5 18: 888468 0 IO-APIC-fasteoi ata_piix, uhci_hcd:usb4, eth0 19: 268 0 IO-APIC-fasteoi uhci_hcd:usb3 23: 300001 0 IO-APIC-fasteoi ehci_hcd:usb1 NMI: 436 172 Non-maskable interrupts LOC: 1810724 1760209 Local timer interrupts RES: 171199 167417 Rescheduling interrupts CAL: 140 6288 function call interrupts TLB: 4071 1963 TLB shootdowns TRM: 0 0 Thermal event interrupts SPU: 0 0 Spurious interrupts ERR: 0 MIS: 0
