Further to my two previous posts about this, in its current configuration, my home system *seems* to be cutting the power reliably, *so* *far*. Here is a description of some items that might be relevant:
1. Linux kernel 2.6.17.13 2. ACPI support enabled in the kernel 3. APM support *not* enabled 4. Using "acpi=force lapic" in the boot line 5. Shutting down with "init 0" 6. In /etc/init.d/halt, removed the "-d" and "-i" options from the halt command I am not yet confident that shutdown is completely reliable, although it is definitely *more* reliable than previously. If I have a definite power-on hang again, I will report back to this thread. -- Power down after shutdown does not work... https://launchpad.net/bugs/43961 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
