Dear all, I am using a Philips Toucam Pro 2 webcam with the program qastrocam-g2 (astronomy program that use some specific functions of the PWC driver). I have been using this program with this camera for a long time on different Linux distributions without a problem. With Ubuntu 12.04, I now get a kernel oops. See bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1010028 I have installed mainline kernel 3.4rc6 on my Ubuntu box to check if the oops was fixed upstream. Now I am not getting the oops anymore but the IOCTL used to get/set the camera parameters are failing: astro@saturn:~$ qastrocam-g2 <init> : Avifile RELEASE-0.7.48-120122-05:53-../src/configure <init> : Available CPU flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow rep_good nopl extd_apicid pni cx16 la <init> : 2200.00 MHz AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ detected Getting Standard: Inappropriate ioctl for device setWhiteBalance: Inappropriate ioctl for device getWhiteBalance: Inappropriate ioctl for device getWhiteBalance: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device ioctl (VIDIOCGWIN): Inappropriate ioctl for device mmap: Invalid argument VIDIOCPWCGDYNNOISE: Inappropriate ioctl for device VIDIOCPWCGCONTOUR: Inappropriate ioctl for device VIDIOCPWCSCONTOUR: Inappropriate ioctl for device VIDIOCPWCGDYNNOISE: Inappropriate ioctl for device VIDIOCPWCGCONTOUR: Inappropriate ioctl for device VIDIOCPWCGDYNNOISE: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCSAGC: Inappropriate ioctl for device getWhiteBalance: Inappropriate ioctl for device VIDIOCPWCSAGC: Inappropriate ioctl for device VIDIOCPWCSSHUTTER: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device getWhiteBalance: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device VIDIOCPWCGAGC: Inappropriate ioctl for device ...
