Subject: dvb-t: crash with smsmdtv/smsdvb (2.6.38.2)
Date: Mon, 11 Apr 2011 00:52:32 +0200 [thread overview]
Message-ID: <20110411005232.24408178@ws> (raw)
Hi,
this happens on 2.6.38.2 (I had the problem in .37 too, therefore I
upgraded) on an ARM machine (Guruplug ServerPlus) with my USB DVB-T
Stick from Hauppauge ("WinTV Ministick") in use with the
corresponding smsmdtv and smsdvb modules. The DVB-T Stick is 24/7 in
use by vdr (http://www.tvdr.de). I get this crash only "every now
and then", like, a couple of hours or a couple of days (but it comes,
for sure). So I can only reproduce it by patience.
dmesg output:
