Red Hat Bugzilla – Bug 19744
Last modified: 2014-03-16 22:17:03 EDT
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
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.
