Hi,
I noticed in November there was a problem running multiple Twinhan DTV
MagicBox II devices, which causes the kernel to lock up. As far as I
could tell, the issue was abandoned - with a copy of the kernel oops
being needed to continue...
Well, I also have multiple vp7045 based tuners (the DNTV version) and
have the same problem. I have an excerpt of the kernel oops text below.
Basically the problem seems to occur if any tuner apart from the first
one is opened, and there is normally a delay (15-20sec?) before the
crash. I am using the CVS driver from the 16/1/06 (the most recent).
Thanks,
Tim.
