>Description:
Some recent fixes addressing kernel panics have allowed the NetBSD atari port 
to install again.  (The last previous version that would install was 1.6.1)  
The next (final?) install blocker is that the bootloader fails to operate.

My system is using an 18gb SCSI disk.  I zero'd the drive before the install.  
I'm installing using default settings.  The install does not use AHDI 
compatible partitioning, it just uses the whole disk for NetBSD.

Here is a disk image from an install of 200812310000Z HEAD:
http://ataritt.dnsalias.org/tt030-halt.img.bz2
This is just a clean install with default options.

While the file is only 60mb compressed, it will decompress to a full 18gb HD 
image.  I took the image using Selfimage (http://selfimage.excelcia.org).  It 
should be just a raw dump of the bits on the disk, I don't think selfimage adds 
any header but I'm not absolutely sure about that.
>How-To-Repeat:
1.  Install the Atari NetBSD port on an Atari TT030.
2.  Observe that upon reboot after the install, "Halting..." is printed to the 
display, presumably by the bootloader.  The system does not boot.

The kernel with the fixes necessary to install on the TT030 without a panic:
