[mplayer:1892] Modules linked in: ipv6 uvcvideo rtl8187 eeprom_93cx6 videodev v4l1_compat <repeats as above> Has anyone else seen this? I'm running with some additional patches for smxc911x, LCD and touchscreen so I want to check to see if others are having the same experience before starting to back out patches. I do not see this issue with 2.6.29-rc2 (675e66d8261d3327bc467426f8a7e15ec8ffad2c) and the identical patch set. Thanks!
