Paul Hartman pointed me at the kernel cmdline option log_buf_len=16M. It's kind of confusing that the compile time option is mentioning a limit while the kernel cmdline option is limit free. I forgot about those differences. Attached is a complete log without wrapping (thanks Paul!). I have annotated the events with markers such as '::::::'. If this message fails to make it to the list, then I will post another scribd link. If you exclude the 'ASS want x actual y count z', you see something like this: [ 245.458291] :::::: BOOT COMPLETED:::::: BOOT COMPLETED [ 264.531436] :::::: FIRST CONNECT [ 267.980998] hub 1-0:1.0: state 7 ports 6 chg 0000 evt 0008 [ 267.981026] ehci-pci 0000:00:10.3: GetStatus port:3 status 001803 0 ACK POWER sig=j CSC CONNECT [ 267.981040] hub 1-0:1.0: port 3, status 0501, change 0001, 480 Mb/s [ 268.140048] hub 1-0:1.0: debounce: port 3: total 100ms stable 100ms status 0x501 [ 268.200330] ehci-pci 0000:00:10.3: port 3 reset complete, port enabled [ 268.200349] ehci-pci 0000:00:10.3: GetStatus port:3 status 001005 0 ACK POWER sig=se0 PE CONNECT [ 268.260068] usb 1-3: new high-speed USB device number 4 using ehci-pci [ 268.260103] ehci-pci 0000:00:10.3: Set ASE [ 268.283615] ehci-pci 0000:00:10.3: Clear ASE [ 268.320336] ehci-pci 0000:00:10.3: port 3 reset complete, port enabled [ 268.320356] ehci-pci 0000:00:10.3: GetStatus port:3 status 001005 0 ACK POWER sig=se0 PE CONNECT [ 268.380212] ehci-pci 0000:00:10.3: Set ASE [ 268.396492] ehci-pci 0000:00:10.3: Clear ASE [ 272.467523] :::::: FIRST CONNECTED [ 273.421878] usb 1-3: khubd timed out on ep0in len=0/18 [ 273.421887] usb 1-3: device descriptor read/all, error -110 [ 273.480329] ehci-pci 0000:00:10.3: GetStatus port:3 status 001002 0 ACK POWER sig=se0 CSC [ 273.480360] hub 1-0:1.0: unable to enumerate USB device on port 3 [ 273.480373] hub 1-0:1.0: state 7 ports 6 chg 0000 evt 0008 [ 273.480383] ehci-pci 0000:00:10.3: GetStatus port:3 status 001002 0 ACK POWER sig=se0 CSC [ 273.480392] hub 1-0:1.0: port 3, status 0100, change 0001, 12 Mb/s [ 273.520044] ehci-pci 0000:00:10.3: GetStatus port:3 status 001803 0 ACK POWER sig=j CSC CONNECT [ 273.680032] hub 1-0:1.0: debounce: port 3: total 125ms stable 100ms status 0x501 [ 273.740371] ehci-pci 0000:00:10.3: port 3 reset complete, port enabled [ 273.740384] ehci-pci 0000:00:10.3: GetStatus port:3 status 001005 0 ACK POWER sig=se0 PE CONNECT [ 273.800040] usb 1-3: new high-speed USB device number 6 using ehci-pci [ 278.811392] usb 1-3: khubd timed out on ep0in len=0/64 [ 283.821364] usb 1-3: khubd timed out on ep0in len=0/64 [ 288.831433] usb 1-3: khubd timed out on ep0in len=0/64 [ 288.890296] ehci-pci 0000:00:10.3: port 3 reset complete, port enabled [ 288.890309] ehci-pci 0000:00:10.3: GetStatus port:3 status 001005 0 ACK POWER sig=se0 PE CONNECT [ 288.950036] usb 1-3: device descriptor read/64, error -110 [ 294.071755] usb 1-3: khubd timed out on ep0in len=0/64 [ 296.066223] :::::: FIRST DISCONNECT [ 299.081898] usb 1-3: khubd timed out on ep0in len=0/64 [ 299.902731] :::::: FIRST DISCONNECTED [ 304.092101] usb 1-3: khubd timed out on ep0in len=0/64 [ 304.150290] ehci-pci 0000:00:10.3: GetStatus port:3 status 001002 0 ACK POWER sig=se0 CSC [ 304.150326] hub 1-0:1.0: unable to enumerate USB device on port 3 [ 304.150339] hub 1-0:1.0: state 7 ports 6 chg 0000 evt 0008 [ 304.150348] ehci-pci 0000:00:10.3: GetStatus port:3 status 001002 0 ACK POWER sig=se0 CSC [ 304.150358] hub 1-0:1.0: port 3, status 0100, change 0001, 12 Mb/s [ 304.310035] hub 1-0:1.0: debounce: port 3: total 100ms stable 100ms status 0x100 [ 309.605509] :::::: SECOND CONNECT [ 315.282186] hub 1-0:1.0: state 7 ports 6 chg 0000 evt 0008 [ 315.282209] ehci-pci 0000:00:10.3: GetStatus port:3 status 001803 0 ACK POWER sig=j CSC CONNECT [ 315.282223] hub 1-0:1.0: port 3, status 0501, change 0001, 480 Mb/s [ 315.440046] hub 1-0:1.0: debounce: port 3: total 100ms stable 100ms status 0x501 [ 315.500395] ehci-pci 0000:00:10.3: port 3 reset complete, port enabled [ 315.500410] ehci-pci 0000:00:10.3: GetStatus port:3 status 001005 0 ACK POWER sig=se0 PE CONNECT [ 315.560049] usb 1-3: new high-speed USB device number 7 using ehci-pci [ 318.790037] :::::: SECOND CONNECTED [ 320.572060] usb 1-3: khubd timed out on ep0in len=0/64 [ 325.582075] usb 1-3: khubd timed out on ep0in len=0/64 [ 330.591811] usb 1-3: khubd timed out on ep0in len=0/64 [ 330.652588] ehci-pci 0000:00:10.3: port 3 reset complete, port enabled [ 330.652604] ehci-pci 0000:00:10.3: GetStatus port:3 status 001005 0 ACK POWER sig=se0 PE CONNECT [ 330.710039] usb 1-3: device descriptor read/64, error -110 [ 335.830087] usb 1-3: khubd timed out on ep0in len=0/64 [ 339.241131] :::::: SECOND DISCONNECT [ 340.842057] usb 1-3: khubd timed out on ep0in len=0/64 [ 343.359064] :::::: SECOND DISCONNECTED [ 345.852058] usb 1-3: khubd timed out on ep0in len=0/64 [ 345.910218] ehci-pci 0000:00:10.3: GetStatus port:3 status 001002 0 ACK POWER sig=se0 CSC [ 345.910252] hub 1-0:1.0: unable to enumerate USB device on port 3 [ 345.910265] hub 1-0:1.0: state 7 ports 6 chg 0000 evt 0008 [ 345.910275] ehci-pci 0000:00:10.3: GetStatus port:3 status 001002 0 ACK POWER sig=se0 CSC [ 345.910284] hub 1-0:1.0: port 3, status 0100, change 0001, 12 Mb/s [ 346.070032] hub 1-0:1.0: debounce: port 3: total 100ms stable 100ms status 0x100
