Hi, I'm a new IVTV user, and hopefully future MythTV enthusiast. I recently bought an ASUS Pundit P1-AH2 with a Hauppage 150 capture card to use as a MythTV and fileserver box. I have been struggling with getting Myth up and running well, ever since putting it together. I'm using the Ubuntu 6.10 (Edgy Eft) distribution. I installed IVTV 0.7.4 last week and all seemed well at first, I could bring up mplayer on /dev/video and see live TV come up, even though my audio was currently busted. After updating my kernel from 2.6.17-10-generic to 2.6.17-11-generic (using the Ubuntu synaptic updater to bring my system "up to date"), and I'm sure several other config changes to try and get audio, samba, and mysql working, I noticed the next time I booted under 2.6.17-11 it broke at the IVTV section of initialization. The relevant chunk of my dmesg is pasted below. I have been a Unix hacker of mostly Sun/Solaris for very many years, but fairly new to Linux itself, so some things, like module loading and kernel compiles, are unfamiliar to me. Where it seems to really go south is at 'BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000'...
Any help in figuring out what went wrong would be appreciated! I'd love to remain a loyal Linux/MythTV enthusiast, but I'm a little frustrated right now... --Roger [17179583.548000] ACPI: PCI Interrupt 0000:00:05.0[A] -> Link [APC7] -> GSI 16 (level, low) -> IRQ 217 [17179583.548000] PCI: Setting latency timer of device 0000:00:05.0 to 64 [17179583.548000] NVRM: loading NVIDIA Linux x86 Kernel Module 1.0-8776 Mon Oct 16 21:56:04 PDT 2006 [17179583.800000] input: PS/2 Logitech Mouse as /class/input/input4 [17179583.800000] parport: PnPBIOS parport detected.
