IDE and PCI

[Marco Schramel]

Hi

we runs a 2.4.25 on a custum board (MPC8270). We use compact flash over UPM. All runs fine.
But if i config in the pci bus the i/o accesses on compact flash will fail. The kernel booting fails and it hangs up.
At the same time i can read out the cf registers with bdi. 
It crashes on the first INB() call in ide_probe.c.   "stat = hwif->INB(hwif->io_ports[IDE_STATUS_OFFSET]);". Without pci it works fine.

Any ideas?

Thanks in advance
Marco
