[Prism54-users] kernel: prism54: pci_request_regions failure (rc=-16)

[Jörg Esser]

Hi list,

I have a EPIA -MII Motherboard with a Netgear WG511 running kernel 
2.4.26 and the prism cvs driver.

When the kernel boots I get the following error:
May  3 21:29:16 vdrclient kernel: cs: cb_alloc(bus 2): vendor 0x1260, 
device 0x3890
May  3 21:29:16 vdrclient kernel: PCI: Failed to allocate resource 
0(e6404000-e6404fff) for 02:00.0
May  3 21:29:16 vdrclient kernel: PCI: Enabling device 02:00.0 (0000 -> 
0002)

When I remove the card and reinsert it I get the following output:
May  3 21:30:49 vdrclient kernel: cs: cb_free(bus 2)
May  3 21:30:53 vdrclient kernel: cs: cb_alloc(bus 2): vendor 0x1260,

When I try it the second time I get this:
May  3 21:31:33 vdrclient kernel: cs: cb_free(bus 2)
May  3 21:31:36 vdrclient kernel: cs: cb_alloc(bus 2): vendor 0x1260,

The lspci output:

lspci -vvv -s 02:00.0

So now my question is what means:

PCI device memory region not configured; fix your BIOS or CardBus 
bridge/drivers


And how can I solve this ?



Thx,
