kernel-2.6.17-1.2145_FC5 still won't boot Promise Raid 0 LVM Set

[Andrew Gray]

Under kernel-2.6.16-1.2133 my system boots a raid 0 volume on a Promise
PDC 20376 that looks like:-

[root at www ~]# dmraid -s
*** Active Set
name   : pdc_fiagfhab
size   : 625163264
stride : 128
type   : stripe
status : ok
subsets: 0
devs   : 2
spares : 0

All FC5 kernel-2.6.17's including 2145  won't boot on my system. The
boot volume is a raid
0 array on a Promise PDC20376 (FastTrak) :-

#Loading jbd.ko module
#Loading ext3.ko module
#Locading dm-mod.ko module
#device-mapper: 4.6.0-ioctl (2006-02-17) initialised:
dm-devel at redhat.com
#Loading dm-mirror.ko module
#Loading dm-zero.ko module
#Loading dm-snapshot.ko module  
#Making device-mapper control mode 

Kernel 2.6.17-2145_FC5 Then hangs !!

I am presuming kernel-2.6.17 kernels doesn't boot because it is not
recognising my LVM volume setup with 2.6.16 kernel
using /dev/mapper/pdc_fiagfhabp2 on the Promise PDC20376. Maybe it has
changed the device mapper name for this device? :-

                                ]
                        }
                }
        }
}

Any ideas how to debug the boot problem with Kernel 2.6.17 FC5 and
Promise RAID controllers when the system won't boot with a 2.6.17 FC5
kernel?
