[vdr] AW: Re: AW: Re: EPG scan cause high load and AC3 drop outs

["Roland Praml" <pram2000@web.de>]

Hi,

My VDR crashed 3 times since I've updated  to 1.1.25
(I don't know why because nothing appeared in the log-files and I
haven't a VGA card in the system. Only CAPS-LOCK and SCROLL LOCK
were blinking when the crash occurs.)

I don't know if I can track down my problem to the AC3-Plugin, but
the crash occured under the following conditions:

1. Tuned channel was PRO-7 (with DD/2.0 Audio)
2. I was copying files over the network and
3. I made a backup from one HD to an other

My Hardware (As far I see no IRQ is shared)
WINTV-DVBs 		IRQ 12
WINTV Nova 		IRQ 11
Network RTL8139 	IRQ 10
Audio CM 8738 	IRQ 9
IDE0/1 		IRQ 14/15
AMD K6/2-450@416MHz
linuxdvb 1.0.0-pre2 driver

Now I've set the LATENCY_TIME to 80 and use  the hw_sections=0 option
(whatever that means) and the last hour the system runs stable at least
for the last hour...
but refering to "cat /proc/interrupts" I get a Interrupt rate of about
1000 INTs/sec if AC3 output is active (if not INT-rate is about 50/sec)
I find this is a little bit high comparing my other devices:

uptime is ~1:02 hours
