Hello, I’m using the last
version of the CVS drivers for kernel 2.4. I know the drivers for kernel 2.4
are old and unmaintained, but I can’t use the kernel 2.6 because I’m
using an application not compatible with it. However, in order to use it, I
have applied some of the patches applied after in the 2.6 version. For example,
the one to avoid kernel oops when using a smp processor. I have also reviewed all the
fixes applied to the driver in the last two years, to try to find a solution to
my problem with no success. After this introduction, I
continue to explain the problem I have. I have a system which is
receiving several PID from a satellite. The modules I use are skystar2.o,
stv0299.o and dvb-core.o. I use szap to tune the card. This system have to be
receiving 24 hours, 7 days a week without stop. I have observed that when it’s
windy it can have a short-time loss of signal and after that the system
automatically re-locks normally and it continues receiving. However, some
times, after one of this loss of signal, szap re-locks but it doesn’t
receive data any more. I try a tcpdump –I dvb0_0 and I got nothing. The
only way to receive again is to unload the driver from the kernel and load it
again. However, this is a problem because it takes to much time. I would like to
fix this random situation. Please, if anyone have an
idea of what is happening or give me some hint to investigate the problem, I world
appreciate. Thank you in advance. Ps. Here is an example
simulated at the office. Having szap running, I plug and unplug the antenna
cable several times until the tcpdump stops receiving but szaps locks again. status status status 03 | signal 8c76 | snr status 01 | signal 9292 | snr 73ec | ber 00000000 |
