-stable (I think this problem has been around long)

64M P90 IDE.

>Description:

kernel with maxusers 1024 panics on boot:

kmem_suballoc: bad status return of 3
panic: kmem_suballoc

>How-To-Repeat:

Set maxusers to 1024 and boot on 64M P90.  I think this is repeatable on
this kind of configuration, but I am not sure whether it happens on larger
configurations.

>Fix:

I do not know.  I guess the actual problem is that "maxusers" does not
really indicate any relation to maximum number of users.  256 is not enough
for host running just an irc server, nothing else.  Increasing NMBCLUSTERS
separately seems to be the "fix" here (in addition to fixing process sizes,
file descriptors and such more standard things).
