So, the newer ffs module is actually _smaller_ than the old one?
Hmmm, another interest data point:
If I boot, and just wait in the boot menu for the 5-second timeout, the
boot fails with the "heap full" message.
However, if I interrupt the boot menu and drop to the prompt, and then
enter "boot netbsd -s" it boots just fine!
As I recall, there were some recent changes to the boot-loader code for
command processing - perhaps something there has not correctly free()d some
heap?
One more example, which would tend to confirm that the boot-loader is not
correctly free()ing memory?
1. Boot
2. Interrupt the countdown, and go to the prompt
3. Execute the 'ls' command (to see what I called my saved kernel!)
4. boot <old-kernel> -s
Fails.
But if I omit the 'ls' command (step 3), it boots successfully.
Yet one more data-point....
I was suspecting the recent changes to the boot code from Havard (in
July) or Jared (in August), so I re-installed the old bootblocks from
another machine. Yet even with the old bootblocks, the bad behavior
occurs.
Note that in all failure cases, the "heap full" message occurs after
loading all the kernel sections, but before the kernel prints its ID
line.
