Dear list,
I've got a linux 2.6 system which locks up (not respoding to keys, blank display - can't be sure if its a kernel panic) totally about twice a day. I've narrowed the problem either to em8300 driver itself or the vdr-dxr3 driver.
Vdr is running nicely without dxr3 plugin and the system is stable more than a day :-)
Vdr with the plugin, random lockups appear. Messages-log may say about ring buffer to be full near the lockup time, but not always. em8300 version 0.15.rc4 and vdr-dxr3 version 0.2.3-cvs20050528.tgz (I've tried some earlier versions too).
I thought about creating a blank-screen and feeding it (instead of tv-picture) constantly to dxr3 and see if the lockups appear. The sources seem quite complicated, thus help will be appreciated ;-)
BR, Jarmo

The obvious questions: which distribution do you use, which kernel version, which vdr version, which dvb-driver version (from kernel or elsewhere)?

- Fedora 3 as a installation. - Hand compiled 2.6.12rc4 - em8300 version 0.15.rc4 - vdr-dxr3 version 0.2.3-cvs20050528.tgz - DVB-driver is the one within the 2.6.12rc4, but with a small patch; budget.c: * grundig_29504_401_pll_set: Line: data[3] = (cpump << 6) | band_select; TO: data[3] = 0xc0; *** Not sure what this does, except it feels like UNC errors disappear.
- Tested with VDR versions 1.3.24 and .25. - Hauppauge Nova-T budget -card (old version) as receiver - Dual SMP box, tested with and without acpi/apic and as single cpu.

You could also try to feed the card with a recording (and loop around playing), using mplayer.
