PR #40571 - NetBSD Atari install fails to prepare 16GB MTRON SSD on ACARD SCSI to IDE bridge

["David Ross" <dross%pobox.com@localhost>]

Not a blocker for me but worth filing a PR anyway.  I just got around to 
trying an install on a different HD and hit this issue.

From the PR:

I'm attempting to install NetBSD 5 (200902030000Z) onto an MTRON 16GB IDE 
SSD which is hanging off an ACARD SCSI to IDE bridge.  The hardware is known 
good and I've done such an install with NetBSD 1.6.1.  I also regularly 
install NetBSD 5 builds onto a Seagate SD318418N and it works great.

That being said, the MTRON setup did cause occasional panics under NetBSD 
1.6.1 where I did not see this with the Seagate.  I was hoping to test if 
that problem still happens on NetBSD 5 but got blocked by this install 
issue.

How to reproduce the install issue:
1.  Zero the MTRON drive.
2.  Boot into NetBSD 5 and begin an install.  Don't choose the option to use 
AHDI partitioning.
3.  Keep the default drive settings, except bump up the swap partition to 
256 MB.
 - Now observe that even though you typed 256, the swap partition size is 
reported to be set at 257 MB.  This doesn't happen with the Seagate.  Maybe 
this is a hint as to what's going on?
4.  Proceed with the install and observe that disklabel fails with:
disklabel: ioctl DIOCWDINFO: Device not configured

5.  After being dumped back at the main installer screen, start the install 
again and follow the same steps.
6.  Now observe a different error as the drive is prepared:
disklabel: partition b: partition extends past end of unit
