So, I was playing with suspend/resume on my laptop to see how well did the new USB stack cope and I was happy that it survived. However... it's really noisy. n 1 16:22:19 phi kernel: uhci_interrupt: host controller halted Jan 1 16:22:19 phi kernel: uhci_dumpregs:696: usbus2 regs: cmd=0000, sts=0020, intr=0000, frnum=061f, flbase=1edae87c, sof=0040, portsc1=0080, portsc2=0080 Jan 1 16:22:19 phi kernel: uhci_dump_qh:769: QH(0xc2d7b680) at 0x0157b682: h_next=0x0157b602 e_next=0x00000001 Jan 1 16:22:19 phi kernel: uhci_dump_qh:769: QH(0xc2d7b600) at 0x0157b602: h_next=0x0157b582 e_next=0x00000001 Jan 1 16:22:19 phi kernel: uhci_dump_qh:769: QH(0xc2d7b580) at 0x0157b582: h_next=0x0157b502 e_next=0x00000001 Jan 1 16:22:19 phi kernel: uhci_dump_qh:769: QH(0xc2d7b500) at 0x0157b502: h_next=0x00000001 e_next=0x0157b480 Jan 1 16:22:19 phi kernel: umass0: at ushub4, port 5, addr 2 (disconnected) This is repeated almost a hundred times before a real suspend. We are probably missing some bits in the uhci_interrupt to cope with suspend. -- Rui Paulo
