>Description:
Since 1.3G i can't boot any kernel anymore. When trying to find the root 
partition the machine hangs for about 10 seconds and then promts the following:

wscons: wskbd0 glued to wdisplay0(console)
<10 seconds>
ncr0: aborting job ...
ncr0:0: ERROR (90:0) (8-0-0) (8/13) @ (script 5b4:50000000).

ncr0: regdump: da 00 00 13 47 08 00 1f 35 08 80 00 80 00 0f 02
ncr0: restart (fatal error).

ncr0: restart (timeout).

I have verified this behaviour with another i386 with ncr which has another 
motherboard, so i don't think it's a hardware failure.

I append the dmesg output for 1.3F as i don't want to type the complete output.
Again, tell me what you need.

>How-To-Repeat:

Build a 1.3G kernel and boot it with a ncr 53c810.
 
>Fix:

absolutely no idea.
