Ah, now i got it. Simply reloading the module kills the card with that nasty
do_IRQ thing (until reboot), but
-> 1) unloading module 2) suspending 3) resuming 4) loading module
actually works. It's kinda dirty solution (with some hackish script in
/etc/pm/sleep.d/), but it works somehow.
Perhaps someday there will be a better solution (power management?).

Well, this doesn't work. If i did tune a channel before or used the dvb card
somehow for watching tv, unloading and reloading the cx23885
module also makes the card unuseable.
In dmesg there's lots of "do_IRQ: 1.161 No irq handler for vector (irq -1)"
messages then. This can only be fixed by rebooting the computer.

TeVii S470 dvb-s2 issues
Hello linux-media people!
I have to problems with my dvb card ("TeVii S470"). I already
filed 2 bug reports some time ago, but no one seems to have
noticed/read them, so i'm trying it here now.
1) "TeVii S470 dvbs-2 card (cx23885) is not usable after pm-suspend/resume"
https://bugzilla.kernel.org/show_bug.cgi?id=16467
2) "cx23885: ds3000_writereg: writereg error on >=kernel-2.6.36-rc with TeVii"
S470 dvb-s2 card
-> https://bugzilla.kernel.org/show_bug.cgi?id=18832
Are these issues known? If so, are there any fixes yet? When will these
get into mainline? Could somebody point me into the right direction.
Can i help somehow to debug these problems?
Where is the correct place to report bugs about dvb/v4l kernel stuff?
Thank you in advance.
Regards,
Boris Cuber

Re: [GIT PATCHES for 2.6.31] V4L/DVB fixes
Hi kernel folks! Problem: Since kernel-2.6.31-rc* my dvb-s adapter (Technisat SkyStar2 DVB card) refuses to work (worked fine in every kernel up to 2.6.30.1). So anything pulled into the new kernel seems to have broken something (at least for me :/). I opened a detailed bug report here: http://bugzilla.kernel.org/show_bug.cgi?id=13709 Please let me know if i can help in finding a solution or testing a patch /whatever. Thank you for your attention ;) PS: As i'm not subscribed to this mailing list, please answer to my address or cc me. -- http://boris64.net 20xx ;) signature.asc Description: This is a digitally signed message part.
