I should have tested that patch better before I sent it... With .uframe_sched=1, my model B's built-in Ethernet chip works fine. I've passed many MB of data through it without issue, including pings, a kernel source download, and package updates. However, I just enabled .uframe_sched=1 on my model A, which has a USB hub and USB wireless dongle attached. Now USB enumeration doesn't work, and booting the kernel is extremely slow, with lots of USB-related messages. I've run that board for a few days straight without issue, with .uframe_sched=0 and periodic network use. Does this imply that .uframe_sched=1 isn't correct for the Pi, or that the code that flag enables has issues? FWIW, the problematic kernel log is below. Unfortunately, I can't debug this much since that Pi is deployed "in production" in my daughter's room, and she's (hopefully...) asleep. I'll also be away starting tomorrow morning until Mon evening. > [ 1.907615] dwc2 20980000.usb: DWC OTG Controller > [ 1.915043] dwc2 20980000.usb: new USB bus registered, assigned bus number 1 > [ 1.924766] dwc2 20980000.usb: irq 33, io mem 0x00000000 > [ 1.932906] usb usb1: default language 0x0409 > [ 1.939969] usb usb1: udev 1, busnum 1, minor = 0 > [ 1.947325] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 > [ 1.956906] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 > [ 1.966981] usb usb1: Product: DWC OTG Controller > [ 1.974570] usb usb1: Manufacturer: Linux 3.13.0-rc1-next-20131125+ dwc2_hsotg > [ 1.984841] usb usb1: SerialNumber: 20980000.usb > [ 1.993202] usb usb1: usb_probe_device > [ 2.000066] usb usb1: configuration #1 chosen from 1 choice > [ 2.008968] usb usb1: adding 1-0:1.0 (config #1, interface 0) > [ 2.018227] hub 1-0:1.0: usb_probe_interface > [ 2.025763] hub 1-0:1.0: usb_probe_interface - got id > [ 2.033990] hub 1-0:1.0: USB hub found > [ 2.040891] hub 1-0:1.0: 1 port detected > [ 2.047796] hub 1-0:1.0: standalone hub > [ 2.054580] hub 1-0:1.0: ganged power switching > [ 2.061983] hub 1-0:1.0: individual port over-current protection > [ 2.070833] hub 1-0:1.0: Single TT > [ 2.076944] hub 1-0:1.0: TT requires at most 8 FS bit times (666 ns) > [ 2.086102] hub 1-0:1.0: power on to power good time: 2ms > [ 2.094549] hub 1-0:1.0: local power source is good > [ 2.102344] hub 1-0:1.0: enabling power on all ports > [ 2.112008] tsl2563 1-0039: model 5, rev. 0 > [ 2.121210] oprofile: no performance counters > [ 2.128318] oprofile: using timer interrupt. > [ 2.135673] TCP: cubic registered > [ 2.142836] NET: Registered protocol family 10 > [ 2.151272] sit: IPv6 over IPv4 tunneling driver > [ 2.159514] NET: Registered protocol family 17 > [ 2.180761] kjournald starting.
