** Description changed: I'm running Kubuntu Karmic on a Dell Studio 1537 laptop. When I establish a successful PPP connection to my ISP (either using pon or wvdial), nothing happens. But when I start issuing commands that will use the PPP connection like: "ping somesite.com" or "apt-get update" at random intervals shows up in the console the following error: BUG: scheduling while atomic: swapper/0/0x10010000 Other less frequent related-errors: BUG: scheduling while atomic: wget/7522/0x10010000 BUG: scheduling while atomic: Xorg/2443/0x10000100 BUG: scheduling while atomic: tail/11677/0x10010000 I tried several things, trying to define the situation (to no avail) or at least to narrow the scenario as much as possible. Using the GUI, sometimes i got either a complete system freeze or a complete unstable system (needing hard reboot in both cases). I thought that the current kernel recovery mode would be the simplest scenario I could try. I also blacklisted all framebuffer related modules (vesafb and fbcon), and all "suspicious" modules (fglrx - from kubuntu repositories and b43). The same error happens all the times, but at random intervals as stated above. I haven't had this problem while running Kubuntu Jaunty at all. The related devices (laptop, usb-serial connector, modem, phone line, etc) are the same while I was running Jaunty and now running Karmic, that is why I don't give too much detail about them here (ask if necessary). I guess here will be attached all the needed information, but feel free to ask me any info or any actions you consider necessary. Thanks a lot ProblemType: Bug Architecture: amd64 ArecordDevices: - **** List of CAPTURE Hardware Devices **** - card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] - Subdevices: 2/2 - Subdevice #0: subdevice #0 - Subdevice #1: subdevice #1 + **** List of CAPTURE Hardware Devices **** + card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] + Subdevices: 2/2 + Subdevice #0: subdevice #0 + Subdevice #1: subdevice #1 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/dsp', '/dev/snd/controlC1', '/dev/snd/pcmC1D3p', '/dev/snd/by-path', '/dev/snd/controlC0', '/dev/snd/pcmC0D0c', '/dev/snd/pcmC0D0p', '/dev/snd/seq', '/dev/snd/timer', '/dev/sequencer', '/dev/sequencer2'] failed with exit code 1: CRDA: Error: [Errno 2] No such file or directory Card0.Amixer.info: - Card hw:0 'Intel'/'HDA Intel at 0xfc400000 irq 22' - Mixer name : 'IDT 92HD73C1X5' - Components : 'HDA:111d7675,1028029f,00100103' - Controls : 23 - Simple ctrls : 14 + Card hw:0 'Intel'/'HDA Intel at 0xfc400000 irq 22' + Mixer name : 'IDT 92HD73C1X5' + Components : 'HDA:111d7675,1028029f,00100103' + Controls : 23 + Simple ctrls : 14 Card1.Amixer.info: - Card hw:1 'HDMI'/'HDA ATI HDMI at 0xcfeec000 irq 17' - Mixer name : 'ATI R6xx HDMI' - Components : 'HDA:1002aa01,00aa0100,00100000' - Controls : 4 - Simple ctrls : 1 + Card hw:1 'HDMI'/'HDA ATI HDMI at 0xcfeec000 irq 17' + Mixer name : 'ATI R6xx HDMI' + Components : 'HDA:1002aa01,00aa0100,00100000' + Controls : 4 + Simple ctrls : 1 Card1.Amixer.values: - Simple mixer control 'IEC958',0 - Capabilities: pswitch pswitch-joined - Playback channels: Mono - Mono: Playback [off] + Simple mixer control 'IEC958',0 + Capabilities: pswitch pswitch-joined + Playback channels: Mono + Mono: Playback [off] Date: Wed Sep 23 23:31:31 2009 DistroRelease: Ubuntu 9.10 HibernationDevice: RESUME=UUID=d576b1b3-b3a5-4009-8db0-46dd009cfda4 IwConfig: - lo no wireless extensions. - - eth0 no wireless extensions. + lo no wireless extensions. + + eth0 no wireless extensions.
