Problems halting/rebooting with 2.4.{5,6}-ac

I have a Tyan Tiger 230 SMP system running dual 1 GHz PIII processors. The processors are of the same lot and revision, bought on the same day. Everything worked fine or some time in regard to halting/rebooting. I was using ac kernels configured with ACPI. At the time of the merge with the Linus stuff which included new ACPI I started configuring with ACPI and ACPI bus management and I could no longer halt the system but rebooting worked OK. As of 2.4.5-ac24 and 2.4.6-ac1 I can no longer halt or reboot my system properly using no power management or ACPI, and APM still displays the message about being broken on SMP. Has anyone seen this problem, is there a fix for it? Another thing I have noticed is that my /proc/cpuinfo file looks like this:

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 8
model name : Pentium III (Coppermine)
stepping : 6
cpu MHz : 999.694

Notice the difference in cpuid level and bogomips values between the two. These processors should be exactly the same, same lot and revision and everything else according to the shrink wrapped Intel retail boxes they came out of. What could be casuing them to show up at different cpuid levels? Thanks for any help with either issue.

Very sorry to have not included more information, when halting or rebooting it now stop at INIT: there are no more processes left at this run level and never actually reboots or halts. To get around it I either have to hit the power/reset buton or use SysReq to reboot it. Thanks again for any help.
