Hello,

I couldn't really find a simple testcase which triggers this
problem, but
I analysed the source code and found that the function prototype
"v4l2_kioctl"
changed between Linux kernel 2.6.27 and 2.6.28: the inode parameter
was removed.
Last time when I updated the em28xx-new I forget this fact. I just
sent a
patch titled "[PATCH] remove inode parameter of typedef v4l2_kioctl
as of 2.6.28".
Could you please apply and test the new version of em28xx-new driver?
Here we can see that "(null)" is written to the output instead of a
readable
input and norm parameter. This usually signals that there might be
some return
value check missing in the code.
This mmap2() calls also do not look like very good: -1 is the fd
parameter which
shall be positive. The -1 is an error code which comes from a
previous system call
and it is not a valid file descriptor.
What can I do against it? I installed the latest release with this
patch applied. This didn't change anything. But notice that I have
Kernel 2.6.27.7-9 anyway, not 2.6.28.x.
Here you see dmesg (interesting lines cut out) again with the new
patch applied. First after trying "ZoneMinder", then after "webcam":

Could you please send your /root/.webcamrc ? (Please change the
password
field in it to *** before sending, if any.)
My .webcamrc can be found here:
