Problem on gentoo, kernel 2.6.14-gentoo-r4

  • I was trying to use qc-usb-0.6.3 (with spin_lock patch) on gentoo, kernel 2.6.14-gentoo-r4, dual Athlon with camera ID 046d:0870.  Kernel module loads ok but testquickcam dumps the core and leaves the system in some strange state.  Any ideas what can be wrong?  Relevant dmesg messages below:
