Dear timecop:
It is just nothing when I modprobe mymodule and modprobe -r mymodule BEFORE
my hardware present.
The bad things happen when I modprobe -r mymodule AFTER my haredware present.

Hi,everyone
I am now developing my own tv card's driver.
While I am debugging, I just found a problem when I used "modprobe -r" to rmmod my driver module, it is like this:
a. When I don't insert my hardware,
modprobe dvb-usb-mymodule.ko and modprobe -r dvb-usb-mymodule.ko
were well executed.
b. First, I insmod my module: modprobe dvb-usb-mymodule.ko
Then, I insert my own hareware.
And if I want to rmmod my module: modprobe dvb-usb-mymodule.ko
It is bad.
The terminal is dead, and the modprobe thread is hanging on and can't be killed. I must reboot to make it.
So, could anybody help me with this issue?
Thank you very much.

How is it that you're inserting driver for your hardware BEFORE the
hardware is present?

Ok, now I'm confused...when I use one filter by calling
dvbdemux_set_section_filter with filter[0] and mask[0] set to something, I
get sections.
If I use two filters by calling dvbdemux_set_section_filter with
filter[0], mask[0], filter[3], mask[3] set to something, I get no sections
at all...
Do I need to do anything special to use multiple filters?
Second, unused filter and mask values are set to 0x00, but how does the
API distinguish between an unused filter/mask pair and a request for all
sections? It seems that if I call dvbdemux_set_section_filter with mask[0]
= 0x00 and filter[0] = 0x00 I do get all sections...

I've dug into the source a bit, and it seems that in
drivers/media/video/bt8xx/bttv-i2c.c, I get an interrupt from the card
without BT848_INT_RACK set, but BT848_INT_I2CDONE is set. If someone
can shed a bit of light on why this might be happening, it would be
greatly appreciated.
Right now, I'm off to see if it works at all in 32-bit mode.

Trent, I believe you're smart enough to see the problem behind
everything .. the license stuff is the smallest part of everything;
I don't steal and obfuscate code and remove the copyrights.
And I for sure will not tell anyone how he has to do his work after a
discussion where I didn't seriously participate.
The code as it is will get removed sooner or later and replaced with a
smaller package which only contains the necessary drivers.
I wonder what you try to gain by bothering about the license there all
you can win is the removal of the code there and the release of the
replacement of the around 80% finished reworked code. So please stay
serious and better try to fix the community problems that something
like that won't happen again.
Markus
