[linux-dvb] old driver: 125 secs, new driver: 4 secs (Re: HOWTO for DVB-C card?)

[Hanno Mueller <kontakt@hanno.de>]

Hi,


while I got the driver to work, now (thanks), as reported in my first
message, the "make insmod" of the old driver still takes forever (125
seconds), while the NEWSTRUCT driver loads very fast (4 seconds).

I hope that the following logs will be helpful. I have changed the
Makefile to log the time of each insmod command.

This box is running an unpatched 2.4.18 kernel. You can find the kernel
configuration at this temporary URL: http://www.hanno.de/dvb/


Greetings,

Hanno
