[vdr] Re: Problems with acpi, linuxdvb and vdr: solution

[Peter Bossy <mls@bossynet.de>]

Hureka!  ;-)

After weeks and months I did find the solution:

The magic word is pci=noacpi in the append-line for the kernel. This 
disables routing of irqs for the pci-bus. So my complete append 
line is now:
append="pci=bios,biosirq,noacpi hdd=ide-scsi"

And as you can see all features (except an  irq for graphics, that I 
actually don t need) is enabled and working fine:

cat /proc/interrupts
           CPU0
  0:      43992          XT-PIC  timer
  1:          2          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  3:          0          XT-PIC  usb-ohci
  4:       1171          XT-PIC  lirc_serial
  5:      66115          XT-PIC  saa7146(1), ohci1394
  7:         18          XT-PIC  usb-ohci
  8:          2          XT-PIC  rtc
  9:          0          XT-PIC  acpi
 10:          0          XT-PIC  CMI8738-MC6
 11:      31684          XT-PIC  saa7146(0), eth0
 14:       2987          XT-PIC  ide0
 15:          2          XT-PIC  ide1
NMI:          0
LOC:      43962
ERR:          1
MIS:          0


Maybe this could be the solution for problems that some of you do 
have, and seemed to be caused by irq-sharing.
