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:
