[linux-dvb] latest mythtv CVS & DEC 2000-t: kernel panic

[Des Herriott <Des.Herriott@oracle.com>]

Hi all,

Here's a puzzler.  A combination of the very latest CVS of MythTV (as of 
a couple of days ago) and the DEC2000-t USB driver causes a complete 
system lockup (i.e. I can't even ping the machine remotely)

The problem occurs when I try to watch live TV.  Initially I thought it 
was a mythfrontend problem, but I then tried a remote frontend, and the 
backend host crashes, every time.

I can reproduce this reliably with a 2.4.23-epia kernel running on EPIA 
M-10000, and also a standard Gentoo 2.4.22 kernel running on a Athlon 
2600+ box.

If I'm not running the frontend on the same host, I see some kernel 
panic type messages appear on the screen, but I haven't been able to 
capture anything yet before they scroll away, followed by a load of 
"__alloc_pages: 0-order allocation failed: gfp=0x20/0" messages.  (If 
the front end is running on the same host, it blanks the screen and I 
don't get to see anything at all)

The problem also seems specific to MythTV - using tzap and mplayer/xine 
to view /dev/dvb/adapter0/dvr0 still works fine.

Sorry I can't be more informative right now; what I'll try to do next is 
get some info on what's changed with the DVB code in mythbackend - I can 
only guess that there's something new in there which is tickling a bug 
in the dec2000-t driver code.

Also, I'd be very interested to hear from anyone else who's tried the 
latest Myth code with any DVB device, not just the DEC2000-t.  Maybe 
it's not a device-specific problem.
