Hello -
I'm unable to find a working environment for saa7134 based RTD
Technologies VFG7350 (two channel, no tuner) using vanilla kernel.
Last working environment was 2.6.25-gentoo-r7 with V4L changeset c7ca307cd4ac.
I'm currently using buildroot with glibc based busybox initramfs for
an x86 embedded system.
I can build 2.6.27, 2.6.30 or 2.6.31, but not yet 2.6.25.
2.6.27.35 "modprobe saa7134" with changeset c7ca307cd4ac:
v4l2_common: Unknown symbol v4l2_device_register_subdev
modprobe: failed to load module v4l2_common: unknown symbol in
module, or unknown parameter
2.6.30.2
Changeset c7ca307cd4ac made it to 2.6.30 mainline and to V4L changeset
e5e3c5df85be.
"modprobe saa7134" result is the same with mainline or either changeset modules:
[ 35.701719] IRQ 11/saa7133[0]: IRQF_DISABLED is not guaranteed on
shared IRQs

[ 35.867599] IRQ 12/saa7133[1]: IRQF_DISABLED is not guaranteed on
shared IRQs
...
[ 36.015256] saa7133[1]/core: hwinit2
[ 65.864162] saa7134_empress: gave up waiting for init of module saa7134.
[ 65.864244] saa7134_empress: Unknown symbol saa7134_devlist
[ 95.862494] saa7134_empress: gave up waiting for init of module saa7134.
[ 95.862569] saa7134_empress: Unknown symbol saa7134_s_std_internal
...
It appears second call to request_module("saa6752hs") in v4l2-common.c
v4ls_i2c_new_subdev() hangs for a few minutes.
The i2c address (0x42) for both channels is correct.
What could I look at next in either 2.6.30 or 2.6.27?
Note: v4l-dvb tip has much regression WRT this card, so I'm not using it yet.
I include 2.6.30 + e5e3c5df85be dmesg with some personal dprintk output below.
Thank for any help,
Gordon
