I've also been experiencing disconnects with my laptop (testing hardy before deploying to my main mythbox) I put the following in as a ubuntu bug report as well bu I have a feeling it's a kernel issue... Happy to help with the ongoing fight for stability! I get the same behaviour on my HP nx6125 laptop with both a nova-t and nova-t diversity stick. Either attempting to scan for, or watch dvb channels results in the following: MT2060: successfully identified (IF1 = 1220) [ 589.459712] input: IR-receiver inside an USB DVB receiver as /devices/pci0000:00/0000:00:13.2/usb3/3-8/input/input16 [ 589.470534] dvb-usb: schedule remote query interval to 150 msecs. [ 589.470540] dvb-usb: Hauppauge Nova-T Stick successfully initialized and connected. [ 606.300175] hub 3-0:1.0: port 8 disabled by hub (EMI?), re-enabling... [ 606.300181] usb 3-8: USB disconnect, address 11 [ 606.312990] mt2060 I2C write failed [ 608.563167] mt2060 I2C write failed [ 608.563243] mt2060 I2C write failed (len=2) [ 608.563246] mt2060 I2C write failed (len=6) This was with the latest mercurial build from v4l-dvb but this doesn't seem to fix things and displays the same as the stock kernel modules. There were some disconnects with previous ubuntu kernel versions (gutsy and previous) but not nearly as frequent as is now happening. Looks like it's probabably an upstream issue as I've read of several other sufferers even with vanilla kernels. Could be my usb chipset or something more generic, lspci is below. Please let me know if I can provide any further debug. david@davslaptop:~$ lspci 00:00.0 Host bridge: ATI Technologies Inc RS480 Host Bridge (rev 01) 00:01.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge 00:04.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge 00:05.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge 00:13.0 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller 00:13.1 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller 00:13.2 USB Controller: ATI Technologies Inc IXP SB400 USB2 Host Controller 00:14.0 SMBus: ATI Technologies Inc IXP SB400 SMBus Controller (rev 11) 00:14.1 IDE interface: ATI Technologies Inc IXP SB400 IDE Controller 00:14.3 ISA bridge: ATI Technologies Inc IXP SB400 PCI-ISA Bridge 00:14.4 PCI bridge: ATI Technologies Inc IXP SB400 PCI-PCI Bridge 00:14.5 Multimedia audio controller: ATI Technologies Inc IXP SB400 AC'97 Audio Controller (rev 02) 00:14.6 Modem: ATI Technologies Inc SB400 AC'97 Modem Controller (rev 02) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon XPRESS 200M 5955 (PCIE) 02:01.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5788 Gigabit Ethernet (rev 03) 02:02.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) 02:04.0 CardBus bridge: Texas Instruments PCIxx21/x515 Cardbus Controller 02:04.2 FireWire (IEEE 1394): Texas Instruments OHCI Compliant IEEE 1394 Host Controller 02:04.3 Mass storage controller: Texas Instruments PCIxx21 Integrated FlashMedia Controller 02:04.4 SD Host ... dh _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
