For starters, it breaks savecore and domain lookups:

savecore: can't find device 3536/854608
ntpdate[111]: can't find host azenomei.falu.nl
ntpdate[111]: no servers can be used, exiting

(with no reply)
00:50:48.441532 azenomei.falu.nl > xzan.falu.nl: icmp: echo request

and pings are not replied to anymore.

Pings from the vax are also not replied by the alpha??? tcpdump, running
on the alpha can see them though.

I briefly thought I had not turned off all IPsec stuff on the alpha side
(azenomei) but  since tcpdunp shows this stuff in the clear, that cannot
be the case.

Looking at netstat -s gives apparently the answer:

ip:
        42720111 total packets received
        195 bad header checksums			(and rising)

So if -O0 really breaks all that stuff it will not be very useful for
testing. At least the checksum algorithm is affected, maybe that gives a
hint for what's wrong with IPsec.
