Hi; I got a VERY weird problem. My system:
PIII 600/128 RAM, 20 Gb HD, SBLive!, NVidia TNT2 (M64), Booktree Bt878 TV
card with FM tuner and remote control. RH7.
Out-of-the-box, all works except the 3D acceleration (for obvious reasons,
with a little tweaking it gets perfect), and the TV card (no sound; the
bttv driver in the kernel is WAY too old).
My modem velocity was (as always) great (4.85 Kb/s average, with a US
Robotics 56k message modem, extern).
So, I recompile my kernel (2.2.17, vanilla). I have no usb (nor 4 GB of
memory), so I have little care about most of the zillion patches that came
with the 2.2.16 shipped with RH7.
I just apply the i2c-2.5.2 (from lm_sensors) patch (bttv 0.7.43 needs it).
I recompile, recompile and install the modules, all right and clean. All
the other modules compiled with no problem at all (bttv 0.7.43, NVidia
0.9-5, and LIRC 0.6.2, for my remote control). All seems to be great.
BUT, when I connect, I realize that the conection speed drops horrible
(about 1.5 Kb/s). I've no idea why (I changed back to the 2.2.16-22 shipped
and the velocity gets normal again, so it's the kernel or some of the
modules). And the options for net, ppp etc. are the same (I checked one by
one).
So, I try to compile all the modules for 2.2.16-22. I apply the i2c-2.5.2
patch over all the other patches (I download the kernel-source-rpm),
recompile the modules and put all the i2c-xxx.o in the right place (bttv
needs the new i2c stack). It works.
I compiled again bttv. It works (whit not a single problem). Same with my
NVidia.
But when I try to compile lirc-0.6.2, kgcc complains:

================================================================================
(BTW; why you guys ship the 2.4.0 headers in the second CD, and install the
same with a 2.2.16 kernel? (yes, there is two kernel-headers-2.4.0 rpms in
the distribution).
So, my question:
You put some optimization in pppd, or something that another kernel build
smash the velocity of the conection?
Because I don't understand what happen, and I really like my remote control
(it's the coolest thing in earth :)
So, please answer this.
(Or you can make a
kernel-with-latest-i2c-and-latest-bttv-2.2.18-prewhatever RPM...
