True, but it's failing for single CPU systems (like mine), too.

In .../fs/proc/proc_misc.c:kstat_read_proc(), the cpu line is
into the D
state, and then vmstat, ps, top, et al. would go D. Now, of course the
problem was that the swap partition was bigger than the physical media,
but there was no error message at all, just procs stuck in D.
Probably there should be an error message, or something.

Yup, I can't make it

happen at all? Do I need to configure some out-of-memory thing?

So, presumably, near the end of the loop list->next is NULL and
the line
struct resource_list *ln = list->next;
causes the oops.

that could be coincidence.
It must be Florida's fault.

You might try that. I have floppy.o configured as a module, also. Try
