Hi guys! I know you must be busy with lots of stuffs there. I am sorry to send you a request for the kernel patch 16936 at http://patchwork.kernel.org/patch/16936/ Basically it fixes some bugs and adds support for a Topro-chip-based webcam, for which I have long desired. I tried to build a module to replace gspca_t613.ko but failed with a strange error. It seems not due to vermagic-incompatibility. Here is the output of modinfo: filename: gspca_t613.ko license: GPL description: GSPCA/T613 (JPEG Compliance) USB Camera Driver author: Leandro Costantino <le_costantino@pixartargentina.com.ar> alias: usb:v17A1p0128d*dc*dsc*dp*ic*isc*ip* depends: gspca_main,usbcore vermagic: 2.6.30-1-686 SMP mod_unload modversions 686 filename: gspca_t613.ko.bak license: GPL description: GSPCA/T613 (JPEG Compliance) USB Camera Driver author: Leandro Costantino<le_costantino@pixartargentina.com.ar> alias: usb:v17A1p0128d*dc*dsc*dp*ic*isc*ip* depends: gspca_main,usbcore vermagic: 2.6.30-1-686 SMP mod_unload modversions 686 As you may see here, the one without .bak suffix is what I compiled with debian's linux-source-2.6.30 package patched with 16936 and the other is the official module shipped with linux-image-2.6.30-1-686. I checked the dmesg output it says both gspca_t613 and gspca_main (if I replace it too since it is depended by t613) might cause an error: [23074.336118] usb 4-1: USB disconnect, address 3 [23077.012070] usb 4-1: new full speed USB device using uhci_hcd and address 4 [23077.185600] usb 4-1: New USB device found, idVendor=06a2, idProduct=0003 [23077.185609] usb 4-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [23077.185755] usb 4-1: configuration #1 chosen from 1 choice [23129.832516] gspca_main: no symbol version for module_layout [23133.662315] gspca_main: no symbol version for module_layout [23715.574510] gspca: main v2.5.0 registered [23715.574799] gspca_t613: no symbol version for module_layout [24707.969844] gspca_t613: no symbol version for module_layout [25405.247398] gspca_t613: no symbol version for module_layout [25575.909439] gspca_t613: no symbol version for module_layout [25597.327205] gspca_t613: no symbol version for module_layout [26020.020324] gspca_t613: no symbol version for module_layout [26220.121513] gspca_t613: no symbol version for module_layout [26707.562201] gspca_t613: module_layout: kernel tainted.

Here the tainted thing happened when I inserted a wrong version forcefully. But later I corrected the versioning. I can't find some useful links about these errors on the Internet and then I am wondering whether you may put the patch into the debian kernel (since it has been accepted by upstreams already). If you do not have the time at present, could you please tell me what I might do to install the driver? I would really appreciate either. BTW I can still find spca5xx in module-assistant while the module source has already been removed from the previous separate package. That might cause some confusion.
