SubjectPCI & IRQ problems on TI Extensa 600CD
  Hi Martin,

i spent few last nights with my Extensa. This notebook has PCI 2.1 wich
works only under m$ window$ :-(. I tried many version of kernel, 2.2,
2.4 and 2.6 tree and nothing helps me. I tried pci=bios pci=bios,biosirq
kernel options, PCI=BIOS instead of ANY...
Result is always same:
PCI: No IRQ known for interrupt pin A of device 00:04.0.
this cause for example that PCMCIA doesn't work. See attached dmesg log
and other files for details.
In Window$ everythink works OK and IRQ routing table is get from PCI
BIOS.

Any ideas?
