Hello all
Sorry if my message will be a little bit long... :)
I used to have a Mandrake 8.1 with the original 2.4.18 kernel from
Mandrake Update, and everything concerning videocapture and TV-tuner
worked ok.
I recently upgraded to a 2.4.21-0.13mdkcustom kernel which I backported
(hacked) from Mandrake 9.1 distro; nothing else essential changed in my
installation. I did that to support the UDMA of my KT400 chipset. But
the videocapture and grabdisplay in xawtv doesn't work anymore. Upgraded
to bttv-0.7.107; same result. Tried 0.9.11; same result. I patched the
kernel (and bttv drivers) with i2c-2.8.0, which I needed anyway to
support my thermal sensors; nothing changed. After upgrade to the latest
xawtv, the situation is the same: lirc_gpio works ok, tuner works ok,
overlay image is very clean and the driver does not crash; but
grabdisplay renders black screen, VBI and videocapture doesn't work at
all for the TV tuner. I also have a Quickcam Express which captures ok
using the same driver!!!
Everyhting works ok when booting the 2.4.18 kernel, except UDMA and
lm_sensors, but I'd like to have them both! Does somebody have any idea
why this happens? Trying to install a new linux from scratch would be
suicide, because I have all my (20GB) work on this HDD; maybe when I'll
buy a new hard drive...
The v4l messages didn't help me very much, because I couldn't see any
change in the IRQ assignments reported to the ones with 2.4.18 kernel.
All that changes is that I have Alsa 0.9.6 running with 2 soundcards,
but I doubt this would be the problem; they work in WinXP as they are,
and at least the Creative Vibra 128 runs also when I boot the 2.4.18
kernel (with Alsa 0.5.3).
I tried various kernel boot parameters (noapic and mem=...)but it didn't
help. Anybody has an idea?
My configuration is a real Christmass tree :) :
AMD Athlon XP 1700+ with an Epox 8K9A motherboard (VIA KT400),
256MB DDRAM 333,
Supergrace GeForce2 MX 200 video card w 64MB SDRAM,
on-board sound VIA 8235 (ALC 650 rev. 0),
PCI Creative Vibra 128 soundcard (es 1371, CS4297 A rev 3),
USB Logitech Quickcam Express,
K-World 878FBK TV/FM card with remote control (almost identical with the
Jetway 878 FBK).
X-windows server is XFree86-4.1.0-17mdk, tests done with xawtv-3.88-0.

The part with "no overlay support" is strange, cause overlay is the only

Thanks for any help!
