Description of problem: When selecting power off in either desktop or gdm the machine goes all the way to the disk flush and sais powering down but it doesn't. Version-Release number of selected component (if applicable): All kernels shipped with RHL 9. How reproducible: I can't say for sure but I have an ABIT BP6 mobo with two PIII CPUs. Steps to Reproduce: 1. Install ABIT BP6 mobo 2. Install RHL9 or RHL8 3. Try to power off with SMP kernel. Actual results: Expected results: Additional info: The cure for this is simple on my machine. I add an apm=power-off to the kernel parameters and it works. I have the same problem on my Fujitsu-Siemens Lifebook E7010 (i815 chipset, P4) but the apm=power-off doesn't help there.
"The cure for this is simple on my machine. I add an apm=power-off to the kernel parameters and it works." Since this crashes on a huge part of the machines out there we can't make this the default unfortionatly. On your laptop, does dmesg show that APM is enabled AT ALL ?
dmesg | grep -i apm sais apm: BIOS version 1.2 Flags 0x1b (Driver version 1.16)
Just to clarify. The laptop bug should be separate from the SMP bug as the laptop isn't a SMP machine. I managed to get the laptop to power down. I found no power management in bios on machine and figured that it must be ACPI only. I recompiled the kernel with no APM and all ACPI and the machine powers down as expected.
The SMP one we can't fix. The laptop will resolve when ACPI is in a state we are happy to ship it
