Message-Id: <200709172027.26325.mark.hagger@ntlworld.com> Date: Mon, 17 Sep 2007 20:27:26 +0100 From: Mark Hagger <chhagger@...glemail.com> To: linux-kernel@...r.kernel.org, mxhaard@...rs.sourceforge.net Subject: kernel oops with 2.6.2x kernels and gspca module Hi, I'm unable to use the gscpa module to drive my webcam. As soon as the webcam is plugged in the following sort of kernel crash happens. With much older kernels (2.6.19 or so) from earlier this year I did have this camera working for a while, but since upgrading to later kernels I've had no luck at all. Regards, Mark Linux whisky.alcohol 2.6.22.2-42_1.cubbi_suspend2.fc6 #1 SMP Mon Aug 20 01:28:07 CEST 2007 i686 athlon i386 GNU/Linux Sep 17 20:14:24 whisky kernel: usb 2-2: new full speed USB device using uhci_hcd and address 2 Sep 17 20:14:24 whisky kernel: usb 2-2: configuration #1 chosen from 1 choice Sep 17 20:14:25 whisky kernel: v4l1_compat: no version for "struct_module" found: kernel tainted.
