Now I have the same trouble, "Floating point exception".
In my case, the message was "BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE
WITH THOSE IN FIRST ALTERNATE, Floating point exception (core dumped)".
When I set 1880845 kbytes to sd1a, a floating point exception error occurs
at fsck. I made partition with APS273 and mkfs showed no errors. Although I
tried from the partition several times, the results were same. Now I'm using
the disk with the error.
When I divided less than 1 giga byets to sd1a, there were no error with fsck.
The formatting procedures are all the same except the size of the partition
divided to NetBSD.
I also tried 1.5 giga bytes partition in vain. But I didn't try 1.1 giga 
byte. So I am not sure that threshold is 1 giga bytes exactly.
