 I saw the similar problem (i.e. an updated new kernel was not stored
 as /netbsd but /netbsdFoo name so the old kernel was loaded after upgrade)
 on upgrading from NetBSD/i386 9.1 to 9.2.
 
 Full dmesg of the machine is here:

 This machine has a traditional MBR partition and also has Windows 10
 partition. NetBSD is installed as wd0a in the last MBR partition.

 IIRC I choose all default sysinst options (except the first
 "b: Upgrade NetBSD on a hard disk") during installation and
 saw no particular error messages (but not sure).
 
 Note the /dev/wd0a is mounted with option "log".
 (I'm not sure if sysinst checks existing options in fstab(5).)
 
 I have not tried to reproduce it, but I'll try how it goes 
 to upgrade 9.2 to 9.2 again.
