Description Matthias Pitzl 2010-07-14 06:22:02 UTC 
When doing a channel scan with my Haupauge WinTV Nexus-S rev 2.3 card, i
get an kernel oops. Seems to be a general problem not only with this
kernel version. Unfortunately i only have a trace for 2.6.43-rc7 but
it's the same trace as i get with kernel versions 2.6.32-3 and 2.6.32-5.

I also tested with another mainboard of Intel, also with an Atom CPU. Same crash. Card has been changed too with another Nexus-S card, also no change, kernel is still crashing when scanning for channels.

This can be easily reproduced using the following command:
scan -v /usr/share/dvb/dvb-s/Astra-19.2E

The crash happens after a short random time.

I tried also the different firmware versions for ths DVB-S card but this
doesn't seem to make any difference. I already sent a bug report to
linux-media@vger.kernel.org.

I also tried to start the kernel with nosmp, noapic, noacpi but this
also does not fix the problem.
