I finally got some time for more testing, and I booted this very same
2.5.25-rmap-slablru kernel on the same machine, and this time it booted

  2.5.27-rmap-slablru I meant to say.

just fine. Then I began to exercise the box a little by running dbench
with increasing numbers of clients.  At 28 clients, I got this:

On closer inspection, these errors began at 6 clients.

(31069) open CLIENTS/CLIENT16/~DMTMP/WORDPRO/BENCHS1.PRN failed for handle 4148 (Cannot allocate memory)
(31070) nb_close: handle 4148 was not open
(31073) unlink CLIENTS/CLIENT16/~DMTMP/WORDPRO/BENCHS1.PRN failed (No such file or directory)

Right after starting 32 dbench clients, the box locked up, no longer
responding to the keyboard.  It did respond to pings, but nothing else.

This hardware does run other kernels successfully, most recently
2.4.19-rc3-ac3 and dbench 128 (load over 100).

I then tried rebooting 2.5.27-rmap-slablru with /home mounted as ext3,
and immediately after starting dbench 1, I got this message about 10
times or so:

ENOMEM in do_get_write_access, retrying.

And the box was locked up.  Next time, I'll have CONFIG_MAGIC_SYSRQ=y.
Meanwhile, it is running the dbench 1 to 64 series under 2.4.19-rc3 with
no problems at all.
