I am now running 4.9-current kernel (from 12th March, ohci.c still at version 1.103) and userland bits from 4.8-release. The uow device is now attached to Belkin F5U219 Rev 4 PCI USB card, the list now looks like this:
# usbdevs -v Controller /dev/usb0: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), NEC(0x1033), rev 1.00 port 1 powered port 2 powered port 3 powered Controller /dev/usb1: addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), NEC(0x1033), rev 1.00 port 1 addr 2: full speed, power 100 mA, config 1, product 0x2490(0x2490), vendor 0x04fa(0x04fa), rev 0.02 port 2 powered Controller /dev/usb2: addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), NEC(0x1033), rev 1.00 port 1 powered Controller /dev/usb3: addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), Compaq(0x0e11), rev 1.00 port 1 powered port 2 powered port 3 powered # I completed another exercise with plugging/uplugging the uow device with various timeouts of removal/insertion. My testing "methodology": for timeout in 0.3s 0.5s 1s 1.5s 2s 2.5s 3s; do unplug wait for timeout plug done Tested with both on-board USB and PCI USB. No panics happened. I got lots of messages like this: uow0: cmd failed, type 0x01, cmd 0x0029, param 0x0000: IOERROR uow0: cmd failed, type 0x00, cmd 0x0000, param 0x0000: IOERROR ohci_freex: xfer=0xd0deb900 not busy, 0x46524545 onewire0 detached uow0 detached uow0 at uhub3 port 1 "vendor 0x04fa product 0x2490" rev 1.00/0.02 addr 2 onewire0 at uow0 uow0: read failed, len 1: CANCELLED uow0: cmd failed, type 0x00, cmd 0x0000, param 0x0000: IOERROR uow0: cmd failed, type 0x01, cmd 0x0021, param 0x0000: IOERROR uow0: cmd failed, type 0x00, cmd 0x0000, param 0x0000: IOERROR uow0: cmd failed, type 0x01, cmd 0x0029, param 0x0000: IOERROR uow0: cmd failed, type 0x00, cmd 0x0000, param 0x0000: IOERROR uow0: cmd failed, type 0x01, cmd 0x0029, param 0x0000: IOERROR uow0: cmd failed, type 0x00, cmd 0x0000, param 0x0000: IOERROR uow0: cmd failed, type 0x01, cmd 0x0029, param 0x0000: IOERROR uow0: cmd failed, type 0x00, cmd 0x0000, param 0x0000: IOERROR ohci_freex: xfer=0xd0deb200 not busy, 0x46524545 onewire0 detached uow0 detached uow0 at uhub3 port 1 "vendor 0x04fa product 0x2490" rev 1.00/0.02 addr 2 onewire0 at uow0 uow0: read failed, len 1: IOERROR So, this PR can be closed. However, the hangs are still happening no matter to which USB the uow device is connected, will do more testing and create separate PR for it once I gather more data.
