I have an OMAP/Zoom1 (3430 LDP). I'm trying to use the
S-Video output, without much success. Today, I grabbed
the latest tree (as least from what I can gather from various
web pages) from git://git.omapzoom.org/repo/omapkernel.git
When I try to use the TV, the kernel crashes immediately:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xd8050440

Notes:
* An older kernel (circa 2008-12-01) does not crash. The
TV output is not correct, but at least it doesn't crash.
* How can I turn off the double printk()? All kernel messages
get duplicated and it makes it terribly hard to use. e.g.
<5>Looking up port of RPC 100003/2 on 192.168.1.100

VFS: Mounted root (nfs filesystem).
VFS: Mounted root (nfs filesystem).
Other kernels (PowerPC, etc) don't suffer from this.
* This kernel version is very unstable - it simply quits after
just a few moments of running. I didn't see this with the
older kernel.
Thanks for any ideas/pointers
