I am running Redhat 7.0 on a Dell Optiplex Gx300 IN general redhat is running well but it appears unable to power off the computer on shutdown - either by halt -p or poweroff. It shutsdown redhat and reports that the system is halted. It then comes back with power off system but DOES NOT shut the power off. It just sits there. I presume that this may be a kernel APM bug???
First guess is that its a Dell bios quirk. Is APM support enabled in the BIOS. What does the kernel /proc/apm file say ?
I do not think that this a a DELL BIOS Quirk. I have tried redhat 6.2 and redhat 7.0 on the same DELL boxes. Redhat 6.2 will power off. Redhat 7.0 will not.
Which kernel (version, UP/SMP, etc.) are you running?
I am running the standard UP kernel included in the 7.0 distribution.
I tell a lie. I was using the enterprise kernel. This WILL NOT powerdown. The UP kernel DOES powerdown. I am quite happy using the UP kernel. The problem obviously resides in the enterprise kernel
The enterprise kernel is SMP. SMP == no APM support.
