I have some 4.3-STABLE boxes that sometimes fail to shutdown
properly. The uname -a date is "4.3-STABLE FreeBSD 4.3-STABLE #0: Mon
May 14 16:37:38 EDT 2001" on one of them, for example.
These are Dell PowerEdge 1550 boxes connected to a Cyclades terminal
server for the serial consoles. The BIOS on these boxes is redirected
to the serial console as well, but that doesn't seem to be the issue.
What happens is I login via the serial console as myself. Then I su
to root and issue a "shutdown now". All processes get killed it
seems, and all services go away (nmap shows no open ports, but ping
answers on both ethernets). The console then just sits there. I
never get the "flushing buffers" messages, nor do I get a prompt for
entering the password to enter single user mode.
The only time I really ever do this is when upgrading the system, so
perhaps it has something to do with installing a new kernel just
before the shutdown. I don't have evidence that this is the cause,
however, since it doesn't happen every time (I've only ever upgraded
about 4 times, mostly from going from 4.3-RC2 to RC3 to STABLE, and
now to a more recent STABLE just ready to make the servers into full
production mode).
Anyone else experience this? I'm kinda feeling like I shouldn't be
logged into the console when I shutdown, as that seems to reduce the
likelihood of such a crash.
The dmesg output on a twin machine is this (I'm waiting for the
datacenter to reset the hung machine right now...)
