Hi, During this summer, I tried to run a Hauppauge NOVA-T USB stick which used to work previously. I tried with the Fedora13 default 2.6.33.x kernel v4l-dvb drivers and with the latest v4l-dvb cvs drivers with the same kernel oops result. I appears that the issue come from a unaligned shared struct between the dib7000m and dib7000p driver, both struct beeing used by shared functions. The patch to solve this issue is attached to this message (the solution is to put dismatching fields at the end of the struct). Could someone with cvs access include this small patch in the v4l-dvb kernel and devel tree? Thank you, Vincent Labie _______________________________________________ linux-dvb users mailing list For V4L/DVB development, please use instead [email protected] [email protected] http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
