I did my "make -j modules" on 64 MB RAM + 130 MB swap test (most things in
.config marked as modules). Passed without problems (2.0.31 was always
throwing warnings or crashing). But then I have left the
machine idle (for about 7 h) and then:

still not cleared after 10mSCPU #1: previous IPI still not cleared after
10mS^IWaiting for 3c509 to discard packet, status 2001.

The "CPU #1: previous IPI still not cleared after 10mS" comes from
arch/i386/kernel/smp.c:1022

The system was idle at that time only the usual deamons
(nfsiod,kerneld,sylogd,klogd,sshd,crond,inetd,named,lpd,rpc.mountd,rpc.nfsd,
atalkd,papd,afpd,sendmail,xntpd(!),httpd,nmbd,xdm,squid) running.

xntpd had some problems 10 minutes before:

No problems afterwards.
