Re: Re: Hauppage Nova-T PCI DVB receiver card fine in 2.6.8, broken in2.6.16
Hi
Thank you very much for your time and attention. Here are some
clarifications (sorry about the crummy formatting).
> This should not be necessary with udev, which should automatically
create your DVB devices. Since you are starting with sarge config files,
I suspect you are missing the required entries in /etc/udev/udev.rules.
Try a web search using keywords debian, udev.rules and the devices you
expect to see. For example, I recently had to add the following
udev.rules entry for a USB remote, for the lirc driver:
> KERNEL="lirc[0-9]*", NAME="lirc/%n"
I do have such an entry for DVB in /etc/udev/udev.rules:
KERNEL=="dvb*", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb};
printf dvb/adapter%%i/%%s$${K%%%%.*} $${K#*.}", \
NAME="%c"
KERNEL=="card[0-9]*", NAME="dri/%k"
> Earlier you report that you (not the "system") created those device
files in /etc/init.d/dvb. Are you saying something else has happened here?
I didn't explain that very well. After 2.6.16 DVB didn't work the first
time, I deleted the device files in case they were still my manually
created ones from 2.6.8. Then rebooting 2.6.16 caused the automatic
creation of the device files.
Hmm. I just remembered I also made an /etc/init.d/dvb entry which calls
a MAKEDEV macro:
#! /bin/sh -e
case "$1" in
start|restart|reload|force-reload)
modprobe dvb-core
cd /dev
MAKEDEV dvb
modprobe grundig_29504-401
;;
stop)
;;
*)
echo "Usage: /etc/init.d/dvb {start|stop|restart|reload|force-reload}"
exit 1
;;
esac
exit 0
I added this to get the DVB going in Sarge. Maybe I should have deleted
that too. Oops.
> It's not clear whether you have differentiated between the effect of
removing hotplug and installing the new kernel. AFAIK removing hotplug
should not have any effect on a non-USB device, while a new kernel
obviously could have an effect.
Well, the 2.6.16 kernel DVB didn't work either before or after purging
hotplug. The 2.6.8 kernel DVB then didn't work until I reinstalled hotplug.
> Are you saying that you replaced udev with hotplug? I don't
understand it because hotplug and udev are not mutually exclusive. If
you are removing udev, then what may have happened that udev was
misconfigured and was somehow breaking or overriding your
manually-created devices in /etc/init.d/dvb. udev replaces /dev and
manually-created device files with a pseudo-filesystem and potentially
overrides them.
Sorry, I was confused when I wrote that. Because I once had devfs/udev
issues between Red Hat 2.4 and 2.6 kernels, I thought udev had been
added somewhere between 2.6.8 and 2.6.16. That was the "adding udev"
that I referred to, not anything I did myself.
> As far as I know, you don't need udev (it's just a convenience) and
you should not need hotplug for your DVB devices, but if you do have
udev installed, it must be correctly configured for your drivers. Your
USB devices only need hotplug if you want them to be automatically
recognized and installed, but otherwise you can manually install.
> My approach would be to get rid of both udev and hotplug for the time
being and manually install and test your drivers seperately. Then when
the driver issues are sorted out, go back and sort out the hotplug and
udev issues, if you need the features they provide.
That is very good advice. It will be a learning exercise for me, but
I'm sure it will pay off. I'll let you know how I get on.
