No Oopses going back to 3 Dec:
ajohnso2@spielplatz:~$ sudo zgrep -i oops /var/log/kern.log*
ajohnso2@spielplatz:~$ sudo gzip -dc /var/log/kern.log.6.gz | head -n 1
Dec 3 06:26:12 spielplatz kernel: [15525239.819366] postgres(22142): floating-point assist fault at ip 40000000003de402, isr 0000040000000008
ajohnso2@spielplatz:~$
Countless floating-point assist fault messages, though. It seems that
PostgreSQL needs some help in this department.

I remember a hang on shutdown for some system during the last week,
but nothing during the kernel package upgrade proper.

OK, so that worked. What change did re-running elilo make? Based on
the MD5sums, there are new initrd and vmlinuz files. Seems like
installing kernel-image-2.6.26-1-mckinley should have done that in its
postinst script.
What happens to the poor user who doesn't know to re-run elilo? (Not
that I expect there are too many "poor users" running ia64 systems.)
Thanks.
