Public bug reported: Since Ubuntu 12.04,
I get a kernel oops when trying to use the Toucam Pro 2 Philips USB webcam with Qastrocam-g2 (not part of Ubuntu repos) an astronomy program that use advanced functions of Philips webcam. Basic usage of the webcam with cheese is still possible. It used to work well before. Tested on Compaq mini 110 netbook (Intel i386) and AMD64x2 desktop. On AMD64x2 desktop/Ubuntu 12.04 Desktop x86-64, I installed: - libqwtplot3d-qt3-0_0.2.7+svn191-4_amd64.deb (http://pkgs.org/debian-sid) - qastrocam-g2_4.8_amd64.deb (sourceforge) I plug in the Philips Toucam Pro 2 USB webcam. I run qastrocam-g2, configure it to use the V4L2 device associated with the Philips Toucam Pro 2 USB webcam in the setting tabs and restart the program. I get a oops and the system hangs. On Compaq mini 110/Ubuntu 12.04 Desktop i386, I installed - libqwtplot3d-qt3-0_0.2.7+svn191-4_i386.deb (http://pkgs.org/debian-sid) - qastrocam-g2_4.9beta20110115_i386.deb (sourceforge) I plug in the Philips Toucam Pro 2 USB webcam. I run qastrocam-g2, configure it to use the V4L2 device associated with the Philips Toucam Pro 2 USB webcam in the setting tabs and restart the program. I get a oops and the system hangs. On Compaq mini-110, I also tried to compile from tarball qastrocam-g2_4.9beta20110115_src.tar.gz (sourceforge) after updating the sources to reflect some changes in the v4l headers for recent v4l versions, but I still get the same result as with the pre-compiled package. Maybe this is the fix (?): http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=ceede9fa8939e40ad0ddb4ad1355f45c6f1d3478 UNAME A for AMD64x2 desktop Linux saturn 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010028 Title: kernel oops Philips webcam PWC driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1010028/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
