Subject: Don't get Sun SPARC T2000 Enterprise booting with any(?) kernel

hi @all,

(please CC: me)

I have a Sun Enterprise T2000 and I try to get Debian onto the disks, but it fails with kernel 2.6.32, 2.6.39, 3.2, the latest stable kernel and 3.3.0-rc5. I have build for my Sunfire v245 a NFS rescue system and I was 3 or 4 times able to boot into my NFS root from the T2000. But in most cases it fails:

I also tried different Debian installer, but older Lenny images and new Squeeze, fails:

Mostly accessing the hardware/ or detection from it.

So, I need some suggestions to get it working. Most problem: I have only 9.4-9.5MB for the kernel + initrd image, otherwise, the OpenBoot Firmware doesn't load it.

If it helps, I can make this host public for some people, to try out, what is the problem.

Also, I put the latest firmware on it, but it helps only a few times to get booting into the NFSroot.
