[V4L] Strange behaviour under 2.4.0test5

	Hi. I found a very strange behaviour under 2.4.0test5. Building bttv in
the kernel didn't help a lot. When I insert the module bttv, with options
card=0 pll=0 exactly as I did in 2.2.16, the system waits one or two minutes
and after that, the prompt gets back. If I enter 'lsmod', it says that the bttv
module is unused, and sadly, if you try to load xawtv, instead of saying
"Oh, you don't have /dev/video, sorry.", system freezes completely and you must
hard-reset the machine.

	One interesting thing is that in the delay, modprobe gets all the CPU
available.

	The path to freeze is:

root@snuggle:~# insmod bttv card=0 pll=0
Using /lib/modules/2.4.0-test5/misc/bttv.o
[after 3 minutes]
root@snuggle:~# lsmod
Module                  Size  Used by
tuner                   2948   0  (autoclean) (unused)
bttv                   52064   0  (unused)
root@snuggle:~# xawtv
(Some messages detecting the card and...)
CRUNCH.

	I have the output of "strace insmod bttv card=0 pll=0", if you could
need it.

	If I don't run xawtv, but try to remove the modules from the kernel,
the messages are these:

root@snuggle:~# lsmod
Module                  Size  Used by
tuner                   2948   0  (autoclean) (unused)
bttv                   52064   0  (unused)
root@snuggle:~# rmmod bttv
root@snuggle:~# lsmod
Module                  Size  Used by
tuner                   2948   0  (autoclean) (unused)
root@snuggle:~# rmmod tuner
Segment violation
root@snuggle:~# lsmod
Module                  Size  Used by
tuner                      0   0  (deleted)
root@snuggle:~#

	I'm using binutils-2.3.11 on Debian potato.

	If you try to insmod again the bttv module...well, I can't wait so much
time :-(. "strace -p <pid-of-insmod>" doesn't says _anything_, and remains
quiet. Stracing this strace gives:

wait4(<pid-of-insmod>, 

	and nothing more.

	I also have the corresponding /var/log/messages entries, and I can send
the output of lspci, lspci -n and lspci -v.

	See you.

		David.
