Mystique SaTiX DVB-S2 [KNC ONE] - Kernel panic

Mystique SaTiX DVB-S2 [KNC ONE] - Kernel panic

[Folnin Vi]

Hello,

I am having problems with Mystique SaTiX DVB-S2 card.

Using the latest drivers from linuxtv.org.

Every time I use the card kernel panic occurs.
For example when trying to scan transponder.

Kernel panic - not syncing: stack-protector: Kernel stack is corrupted 
in: fb40d12f

I have tried to use kexec to make a vmcore dump, but the gdb only shows:
[root@alinux ~]# gdb ./vmlinux ./vmcore.dvb_v4l
...
(gdb) bt
#0  0xc017e781 in ?? ()
#1  0x00000000 in ?? ()
(gdb)

The card on windows works fine.

Is it a driver problem?

Is there a way I could extract more information about this issue?

Any help would be really appreciated.

Some more info:

Have you gained any progress with this problem? - Actually I think this only 
happens when the v4l-dvb is compiled with gcc 4.4 - using gcc 4.3 works around 
it. Can you confirm this?
Besides I am quite clueless what's causing this issue so far.
