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
