Hi.
I'm running my vdr on an up-to-date (with respects to BIOS) ASUS
mainboard P5VD2-X with an Intel Pentium DualCore E2160 (a 65Watts
dualcore at 1800MHz). Kernel version is 2.6.18-4 (from Debian/ctvdr6).
The system has two IDE disks (with DMA enabled of course) and both a
budget (Nova-S) and a full featured (Nexus-S, rev. 1.5 IIRC) DVB-S PCI card.
If I boot 2.6.18-4-486 (which is a non-SMP kernel so only one core is
used), my vdr works perfectly nice. However, when I boot 2.6.18-4-686 or
any other SMP kernel (self-built or not, with Debian/ctvdr patches or a
stock kernel up to version 2.6.22, I tried everything apart from diving
into the code myself), I get the error message quoted in the subject
line (in syslog):
kernel: dvb-ttpci: warning: timeout waiting in LoadBitmap: 0, 1
And vdr seems to retry loading the Bitmap (as further messages of the
kind appear until I kill vdr and remove+reload the DVB kernel modules).
The error isn't 100% reproducible but usually occures when I try to open
vdr's on-screen menu. Once the first message of that kind occures, vdr
isn't responsible to keyboard/LIRC inputs anymore.
Any ideas how to fix this problem? I would really love to be able to use
both cores of my CPU and still have a working vdr.
"lspci -v" output for the DVB-S cards:

"/proc/interrupts|grep -E 'dvb|saa'" says:
50: 1288508186 IO-APIC-level saa7146 (1)
233: 42658103 IO-APIC-level saa7146 (0)
I don't know which hardware interrupts those are mapped from/to and
currently don't know how to find out.
If you need any further data to give a helpful answer, don't hesitate to
ask.
