2.4.21: Reproduceable Oops doing modprobe bttv (ProLink PixelView

[=?UTF-8?Q?Fr=E9d=E9ric_L=2E_W=2E_Meunier?=]

2.4.20 worked fine with bttv-0.7.106.tar.gz. Today I used
2.4.21 with the kernel modules and got a reproduceable Oops
doing modprobe bttv. lsmod shows bttv as (initializing).

modprobe -a tuner msp3400 bttv (or using separate modprobe for
each module).

/etc/modules.conf:

# I2C
alias char-major-89     i2c-dev
options i2c-core        i2c_debug=1
options i2c-algo-bit    bit_test=1

# TV
alias char-major-81     videodev
alias char-major-81-0   bttv
options bttv            card=37 tuner=2 radio=1
options tuner           type=2

I also tested with another 2.4.21 without ACPI.

ksymoops 2.4.9 on i686 2.4.21-ACPI.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-ACPI/ (default)
     -m /boot/System.map-2.4.21-ACPI (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
