Been using Mythbuntu 11.04 x86-64 and no longer have this issue. I've
been testing it for a month and feel comfortable going to this version.

I think I've found the fix for this one - it's described in bug 800527.
Could you try 10.10 with the kernel from the -proposed repository?
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed.
Let us know how that goes.

For the record, I've had some level of success by upgrading to the
current Natty dev build. The steps involved were:
- Run command: update-manager -d
- Click the upgrade button and perform the full upgrade
- Installed the proprietary NVidia driver for my video card (I guess YMMV)
- Undo all the

Title:
Kernel Oops - unable to handle kernel paging request; EIP is at
Instead of rebuilding to 10.04 I decided to try Mythtv0.24+fixes with
the 2.6.36 kernel. After some additional research/user-group posts I
have managed to get my mythfrontend working pretty reliably with smooth
HDTV playback (something I couldn't achieve before). There are a few
glitches when
Tried Ubuntu 10.10 with 2.6.36-020636-generic and MythTV frontend quits,
session logs out and presented with Ubuntu log-in screen same as with
2.6.35. Anyone know if anyone is looking at this otherwise I'll just
rebuild my machines to 10.04.

I have this same oops with my TeVii S470 DVB-S2 card (cx23885 chip) and
Mythbuntu 10.10 with the 2.6.35-24-generic kernel. Mythbuntu 10.04
works fine, but does not run the S470 as it does not have drivers for
it. I tried the 2.6.35-02063508 kernel and that works, but I am a bit
worried about
I have two cards and have been testing with Ubuntu 10.10. The cards are
- TechnoTrend S2-3200 (saa7146)
- TeVii S464 (cx88)
I've been seing the dreadful unable to handle kernel paging request +
mythtv-setup freeze both with the stock 2.6.35 kernel as well as with
the 2.6.32 kernel from 10.04LTS

Update: 2.6.35-23-generic does not fix this problem.
Here's the relevant section of the dmesg. If anyone working on this
would like to see any other log, let me know. This is with a Hauppauge
1800 PVR card. This happens as soon as the video capture is started in
MythTV. Either with Watch Live
I have the same problem with a TBS 6920 DVB-S card. I can zap to any
channel using this card but if I try to scan it will pickup the first
couple of transponders then lock up. Afte this the only way to unlock
the DVB card is to restart the PC
The card is based on the conextant cx23885/cx24116
I believe I have exactly the same problem. I was wanting to upgrade and
fix some completely separate issues with 10.04 install, and found a
FRESH install of 10.10 or the latest patches as of today have this
problem. Mythtv reliably craps out exactly as described in crash posted
in this bug report
Forgot to add that I am using an Hauppage HVR-1800

Anyone know if the newest kernel fixes this problem?
Linux myth 2.6.35-23-generic
Or do I need to get the 2.6.36 from the mainline ppa? if so how is
stability so far?

2.6.36-020636rc8-generic ppa fixed this problem for my Hauppauge 1800, but then
broke the sound for my snd_hda_intel, which I think is this issue but haven't
been able to do a successful compile with the provided patch.

Correction on my last post:
I didn't see a 2.6.35-23-generic offered in the package manager. Latest in the
package manager is still 2.6.35-22-generic, which is experiencing the problem.

Affects me too, with a Hauppauge 1800 card. /dev/dvb is completely
unuseable.
Attached syslog and dmesg incase it helps.

I have a hauppage Nova-T 500 (2 turners) and a usb Avermedia Volar (I
did the scan with this one). I have the same problem. First channel it
finds, it blocks.

This also effects my Happauge HVR-1250. It seems to lock up the mythtv
backend when trying to use this tuner. Please fix as my mythbuntu
system is now useless because it cannot record anything.

I can confirm the same issue with the Dvico FusionHDTV7. Firmware
upload successful, but any attempt to tune in channels using either
MythTV's built-in scanner or the dvb-apps scan utility result in above
bug. Partial dmesg report attached.

I've been experiencing the same issue on my system (Mythbuntu 10.10,
amd64, Happauge HVR-1250). I have successfully installed the linux-
image-2.6.36-rc8 kernel from the mainline PPA and can say that my tuner
is now working successfully.
Someone more adventurous than I might be able to bisect the
I have a Hauppauge 1800. I did a fresh install of 10.10, and I am having
the same problem as above.

My experience is similar to other posts. Recorded PBS

LiveTV, Chanel Scan, etc. all fail with hangs and/or black screens.
Thank you to devs with more knowledge, time, experience, and inherent
worth for looking into this for us.
