I am trying to boot on an ARM-Integrator AP a linux-2.6.9 kernel with u-boot. I tried u-boot-1.1.1 stable and cvs, but both result in "data abort" just at the point of "Starting kernel .... ". Here is the dump from minicom:

That is a rather odd address to have an abort at assuming you're using the uImage obtained from `make uImage` because there are normally NOPs from 0x8000 through 0x801f, e.g.
../BUILD/integrator/default/arch/arm/boot/compressed/vmlinux: file format elf32-littlearm

Has anyone succeeded in booting a 2.6.x kernel with u-boot?
FWIW, I just booted 2.6.10-rc3 bk latest on IntegratorAP with ARM920T processor module using latest u-boot CVS:
