[linux-dvb] 2.6.5 interrupt handling -> kernel panic

[Philip Lawatsch <philip@lawatsch.at>]

Hi,

I'm using the dvb drivers supplied with 2.6.5

I've got one nova, one nova-ci (without the ci module attached)and one 
ff card (rev 1.5).
I'm using vdr on this box.

After leaving this box alone for a while (some hours) i do get kernel 
panics.

The trace i've got looks like this

dvb_dmx_swfilter_section_copy_dump
dvb_dmx_swfilter_section_packet
dvb_dmx_swfilter_packet
scheduler_tick
dvb_dmx_swfilter_packets

And is triggered by Process Swapper (0).

I'm using a single cpu machine, but turned on the preemtive kernel option.


Is there some known bug with 2.6.5 ?

Also, the driver reports
>DVB: registering new adapter (Siemens/Technotrend/Hauppauge PCI rev1.3).

even though i have a 1.5 rev !?


Some info about the system follows.


with kind regards Philip Lawatsch
