Do you have any power saving settings turned on in the bios?
This is a dell computer and it has a power managment option in BIOS. However, I changed it to not-to-save energy mode. After this, I found that the computer restarts rather than hanging.
Looks like some hardware crash to me, otherwise you would have some logs for oops/hangs.
Can you make available somewhere your /var/log/messages (don't send a few MB file to the list) and the /proc/cmdline content ?
You said you used "acpi=off" and acpid disabled is it still the case?
