[U-Boot-Users] problems transferring control to linux (ppc)

we are porting u-boot/linux to a custom board based on mpc8280.
After having made u-boot-1.1.4 work, we tried booting some
test-configured linux 2.6.15 kernels.
If we start u-boot using Trace32 (lauterbach) all goes well and linux
gets loaded, but if we do the same steps disconnecting Trace32, u-boot
seems to work properly, but as soon as the control is transferred to
linux all seems to be hanged, and the last words visible on the serial are:
## Loading RAMDisk Image at 00400000 ...
Image Name: Test Ramdisk Image
Image Type: PowerPC Linux RAMDisk Image (gzip compressed)
Data Size: 1374924 Bytes = 1.3 MB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
## initrd at 0x00400040 ... 0x0054FB0B (len=1374924=0x14FACC)
Loading Ramdisk to 07e4e000, end 07f9dacc ... OK
## Transferring control to Linux (at address 00000000) ...
We are wondering if this is an issue involving u-boot or if this is
related to linux config (in this case sorry for being off-topic).
Thanks for any help!!
