Description of problem:
radio tuner is reseted by gimp
Version-Release number of selected component (if applicable):
since FC1 or so
Steps to Reproduce:
1. listen to the radio
2. start gimp or update the gimp rpm
no more radio listening
leave my tuner alone!
I can't reproduce your problem -- my radio plays flawlessly if I start or update
the gimp. Please provide more info.
What info? I could show you the effect in personal!
FYI, this is a TV card with a radio tuner... not an external one disconnected
from the computer :)
[Tim: I'm Ccing you in case someone opens a similar bug against xsane/sane]
Ahh... interesting. I've tried this out on your machine and found this:
- Updating the gimp package didn't do anything to the running radio (which is to
be expected since it only installs some symlinks, updates the icon cache... in
the %post* scripts)
- Running the gimp _did_ reset the radio, it seemed to come from the xsane
plugin (which tries to determine what scanner-like hardware is present on the
system when starting the GIMP)
- I confirmed this with running the standalone xsane which tries to open
/dev/bttv, /dev/video[0-3] (as configured in your /etc/sane.d/v4l.conf)
- I tracked this to the v4l sane plugin sending the ioctl VIDIOCGCAP to
/dev/video0 (which is incidentally the same TV/radio card that gets reset) in
order to determine the card's capabilities.
To me it looks like the bug is in the bttv driver which resets the _radio_ part
of the card when querying its _video_ capabilities, therefore I reassign this to
kernel. NB: One could argue that the card shouldn't reset anything when querying
any capabilities, but let's not be greedy ;-).
Harald, as a workaround, commenting out the offending lines in
/etc/sane.d/v4l.conf should help.
VIDIOCGCAP is big hint.
bttv_do_ioctl() does the following check before checking ioctl command:
However, ->errors are REset to 0 by bttv_reinit_bt848().
Where they are SEt, you ask? Ha!
Harald, please, test this:

hmm, seek the kmalloc in vmlinuz and toggle some bytes :)

Thomas just saw the problem isn't fixed on Rawhide with
Based on the date this bug was created, it appears to have been reported
