>Description:
I CVSUP'd two Dell PowerEdge 1750 dual Xeon 2.4GHz FreeBSD 6.1 STABLE servers. Following the CVSUP I rebooted into single user mode and installed the new kernel and installworld. On subsequent reboot the system hung while detecting CPU #2 and would not continue. Noticed that the build was 6.2 PRE-RELEASE. I can still boot into safe mode. Alternatively, I can boot into default mode by disabling the second CPU in the Dell BIOS. Please help.
>How-To-Repeat:
Upgrade 6.1 stable on a multiple CPU dell PowerEdge 1750, reboot in to single user mode to install the kernel and world, then reboot and watch it hang...
>Fix:
Boot into safe mode or disable second CPU in BIOS.

     sys/amd64/amd64      local_apic.c 
   Log:
   Since ULE doesn't honor hlt_cpus_mask don't compile code that prevents
   timer interrupt servicing for disabled HTT cores in ULE case. Should be
   probably fixed in ULE code instead, but we have no real maintainer for
   ULE to do it.
