Description of problem:
After changing from a 2.53 GHz PIV CPU w/o HT to a 3.0 GHz PIV CPU w/
HT and the SMP kernel my system won't power down anymore correctly.
I can hear the at least the HDD spins down after the "Power down."
kernel message the rest of the system is still running.
Mainboard is a Gigabyte 8KNXP.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. use a SMP kernel and a PIV HT CPU
2. shutdown the system
3. --> system does not power off
I have the same problem: it gets all the way to the end of shutdown
and then doesn't actually turn off the power. I'm using a P4 2.4CGHz
with HT turned on. Motherboard is an Intel D875PBZ. I'm running
plain FC1 with vmlinuz-2.4.22-1.2115.nptlsmp.
After adding "apm=power-off" to the kernel line in
/boot/grub/grub.conf the system powers down correctly.
The new errata kernel 2.4.22-1.2129.nptlsmp behaves exactly in the
same way. The system will not power down without "apm=power-off". I
thought this had been fixed after reading the changelog for the new
