Should kswapd and klogd ever get "do_try_to_free_pages failed"? when
this happens my machine is destabilized, and pauses briefly from time to
time before locking up or otherwise becoming inert. This is 2.2.16+USB.

That seems to be the place for Andrea Arcangeli VM patch. Get it at:
http://www.kernel.org/pub/linux/kernel/people/andrea/patches/v2.2/2.2.16/mm-fix-*
Or even better, get kernel 2.2.17 and
http://www.kernel.org/pub/linux/kernel/people/alan/2.2.18pre/pre-patch-2.2.18-18.bz2
http://www.kernel.org/pub/linux/kernel/people/andrea/patches/v2.2/2.2.18pre18/VM-global-2.2.18pre18-7.bz2
and get a 2.2.18-pre18-vm, with USB support included.
There is a 2.2.18-pre20 out, but I have not still checked if
VM-global-2.2.18pre18-7.bz2
works on it. It worked for me in -pre19.

Sadly it is not a bug but a VM misdesign (and people are just making
different workarounds that more or less work). I believe that this
solution will break again, as it happened in 2.2.15 and 2.2.16.
Go back to Linux 2.0 - it has the swapper implemented correctly :-)

2.2.15->16 was the major transition in getting stuff right. 2.2.18 should be
pretty reasonable. With Andrea's additional patches its quite nice. If we
add page aging then in theory it'll be as good as 2.2 but in practice who
knows

What about the possibility that kernel shoots processes when the machine
is receiving too much packets and runs out of atomic memory? It didn't
seem to go away in 2.2.16. 2.0 behaved correctly in this case.

Agreed.
