I probably should wait and put all info in one mail, but anyway....


so before adding pci=noacpi
cat /proc/interrupts
           CPU0
  0:     144535          XT-PIC  timer
  1:         10          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  5:      32435          XT-PIC  yenta, eth0, via at pci:0000:01:00.0
  6:          0          XT-PIC  VIA8233
  7:          0          XT-PIC  yenta, ivtv0
  8:          1          XT-PIC  rtc
  9:     100000          XT-PIC  acpi
 12:        113          XT-PIC  i8042
 14:      13474          XT-PIC  ide0
 15:       4088          XT-PIC  ide1
NMI:          0
LOC:          0
ERR:          0
MIS:          0


and after
cat /proc/interrupts
           CPU0
  0:      58094          XT-PIC  timer
  1:         10          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  5:       9948          XT-PIC  yenta, eth0, via at pci:0000:01:00.0
  7:          0          XT-PIC  yenta, ivtv0
  8:          1          XT-PIC  rtc
  9:          0          XT-PIC  acpi, VIA8233
 12:        113          XT-PIC  i8042
 14:      12420          XT-PIC  ide0
 15:       1461          XT-PIC  ide1
NMI:          0
LOC:          0
ERR:          0
MIS:          0


It seems like xine is not dead when it plays now, but I am remote, so no way
to tell until tonight if this solved anything more.  I will keep you posted.
