I am unable to reproduce this with any version 2.6.30.10., 2.6.31.12, 2.6.33.1, 2.6.34-rc4-git2. I turned off the camera many times, removed the PCMCIA card while the USB media was recognized through kernel (not mounted), no luck. I do use it say once a week and the crash I swa for the first time, so I am not much optimistic on reproducibility. :(
Could it be related tot he fact that because the laptop has USB1.1 onboard it loads uhci_hcd first. Eventually when I plugin the PCMCIA card it loads ehci_hcd and the kernel complains it should have been loaded before? Is there a way to tell this in /etc/modules.d/somefile ? I fear I have to compile them into the kernel statically, on this particular setup.
