Hi all,

I've downloaded the linuxppc_2_5 tree with bitkeeper and compiled it for
my prep board I always have the same message :
PCI: Cannot allocate resource region 0 of device 00:0d.0
PCI: Cannot allocate resource region 1 of device 00:0e.0
PCI: Cannot allocate resource region 1 of device 00:11.0
PCI: Cannot allocate resource region 2 of device 00:11.0
PCI: Failed to allocate resource 2 for Symbios Logic Inc. (formerly
NCR) 53c895

and after the sym53c8xx driver give the following :

sym53c895-0: Downloading SCSI SCRIPTS.
scsi0 : sym53c8xx - version 1.6b
scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 0,
lun 0 Inquiry 00 00 00 ff 00
sym53c8xx_abort: pid=0 serial_number=1 serial_number_at_timeout=1
SCSI host 0 abort (pid 0) timed out - resetting
SCSI bus is being reset for host 0 channel 0.
sym53c8xx_reset: pid=0 reset_flags=2 serial_number=1
serial_number_at_timeout=1

Any idea why this continue to fail ?

Standard 2.4 PCI resource handling problems.  #define DEBUG in
arch/ppc/kernel/pci.c and show us your output.  The request_resource()
call is failing.

BAR2 (resource region 2) is the on chip RAM on LSI Logic's 53c8xx SCSI
chips, it's looking for an 8KB allocation in PCI memory space.  If it
doesn't get placed, then the 895 driver can't kick off the bus master
driven transfer to download the scripts into the 895's on-chip RAM.

Here's the result (PCI part) :
