PCI mapping problems? (440EP/Bamboo)

["Andriy Korud" <a.korud@vector.com.pl>]

Hi, I'm trying to make PCI on Bamboo usable at 33MHz and have the =
following problem:
Kernel 2.6.11 with Bamboo patches (either from the list or my own) =
boots, PCI is scanned fine:

PCI: Probing PCI hardware
Scanning bus 00
Found 00:20 [1260/3890] 000280 00
Fixups for bus 00
Bus scan for 00 returning with max=3D00
PCI fixup irq: (0000:00:04.0) got 25
PCI: bridge rsrc 0..ffff (100), parent c01b0f80
PCI: bridge rsrc a0000000..afffffff (200), parent c01b0f64
PCI:0000:00:04.0: Resource 0: afffe000-afffffff (f=3D200)

lspci is also working fine, but when trying to load any driver, kernel =
crashes on first actual device access, i.e. on writew() operation.
When tried to look which address it's trying to access - 0xd1058000 in =
my case - seems confusing for me - should not this address be withing =
PCI address range - 0xa... and withing this device address range - =
0xafffe000-afffffff?
Tracking deeper I've found that this address is taken from calling =
pci_resource_start(pdev, 0) whithing probe function in driver.=20

This problem is generic - at least 3 different pci drivers crash when =
trying to writew() to bad address.

Can anybody give some advice in which direction should I continue my =
debugging?

Thanks in advance,
