Hello, After carefully analyzing the UDC code, I tried to forward port the UDC I am playing with from 2.6.34.10 to 3.2.11 kernel. Everything compiles and links, but when I try `modprobe g_zero`, the following trace happens (log imported at the end of @): [ 36.110506] kernel BUG at fs/sysfs/file.c:573! [ 36.110595] invalid opcode: 0000 [#1] SMP Any idea why this does happen? Thank you, Zoran _______ [ 36.110308] udc max_udc: registering UDC driver [zero] [ 36.110320] gadget: adding config #3 'source/sink'/f817a820 [ 36.110328] gadget: adding 'source/sink'/f5922d80 to config 'source/sink'/f817a820 [ 36.110337] gadget: full speed source/sink: IN/ep3in-bulk, OUT/ep1out-bulk [ 36.110344] gadget: cfg 3/f817a820 speeds: full/low [ 36.110349] gadget: interface 0 = source/sink/f5922d80 [ 36.110355] gadget: adding config #2 'loopback'/f817a760 [ 36.110361] gadget: adding 'loopback'/f5922de0 to config 'loopback'/f817a760 [ 36.110369] gadget: full speed loopback: IN/ep3in-bulk, OUT/ep1out-bulk [ 36.110376] gadget: cfg 2/f817a760 speeds: full/low [ 36.110381] gadget: interface 0 = loopback/f5922de0 [ 36.110387] gadget: Gadget Zero, version: Cinco de Mayo 2008 [ 36.110402] ------------[ cut here ]------------ [ 36.110506] kernel BUG at fs/sysfs/file.c:573!
