Hi Ivan,
which kernel version and kernel headers are you using? Mine are 2.6.23.1
and 2.6.23, but now I am trying to move the kernel headers to 2.6.21
(Angstrom linux works without problems, but are based on different
kernel headers).
uclibc I am using are 0.9.29, alsa 1.0.14.
The failing ioctl is identical both in the working (Angstrom) and not
working versions, and since the kernel is the same (really the same!) I
am thinking that is only a problem between the "glue" of uclibc and
kernel...
I'll keep you informed.
Regards,
ing. Federico Fuga
(sorry for the duplicate mail!)
