[kaffeine-user] Cannot tune DVB-T with a recent kaffeine and 2.6.28

[Pavel T. <pa...@si...>]

Hi!
  I've updated to the svn kaffeine and running linux-2.6.28. From now on, I
cannot tune my DVB. Kaffeine simply writes
ERROR Tuning
: Invalid argument
Frontend closed

In dmesg, the following message appears:
Jan 10 19:33:11 arcus kernel: ioctl32(kaffeine:18628): Unknown cmd fd(15) cmd(40086f52){t:'o';sz:8} arg(fffc3d84) on /dev/dvb/adapter0/frontend0

I was looking at the source, the ioctl which causes the problem is
FE_SET_PROPERTY. Its binary representation seems OK. I've looked to the
kernel sources, turned on dvb_core debugging, and I can see, that the ioctl
comes properly to dvb_frontend_ioctl (I can see it printed in the debug log)
but not to the dvb_frontend_ioctl_properties (not stated in the log).
The source seems clear and I don't know, why it doesn't call it and probably
comes to the dvb_frontend_ioctl_legacy (which doesn't generate the debug log)
and fails there.

The kernel is compiled for x86_64, but the kaffeine is still 32-bit binary.
Any hints ?

With regards, Pavel Troller
