But the system does not shut down. (The fans keep spinning, the LEDs
I have seen this behavior earlier on a system with the SMI interrupt
disabled. I do not know if this the case here, it is just a hint.
Thanks for the suggestion. I didn't see anything related to SMM in the
BIOS menus. However, the system has real-time constraints. Thus, I'd
turn SMM off if I knew how :-)

By the way, some distros bring the CPU in a halted state on a 'halt'
command, instead of powering off (actually very logical). For real
powering off these distros require the obvious 'poweroff' command.
Good suggestion. I'm using sysvinit-2.86

AFAIU, poweroff is equivalent to halt -p
halt (no option) calls reboot(RB_HALT);
poweroff or halt -p calls reboot(RB_POWER_OFF);
man 2 reboot
Alas, when I run 'poweroff' the kernel prints the same information:
Halting.
