Yes, it's a kernel bug but who knows when it will be fixed, even the latest
3.1-rc4 kernel doesn't have the fix.
Please apply the patch to the oneiric ubuntu kernels, like redhat and archlinux
are doing for some time now.
These are extremely popular cameras, and it's very embarassing to sound like
mickey mouse with skype on oneiric installations.
How soon can you apply the patch?
