I am trying out the SMP code for a PC x386 build. When a cyg_thread_delay() gets encountered the system crashes. I tried using a spinlock around the cyg_thread_delay() but it makes no difference. I have an older version of eCos about 3 years old. Any suggestions would be helpful.

I have found that pcmb_smp.c finds only 1 entry for a CPU in the ACPI table. I assume this is the starting CPU. How do I get the MB to report all CPU's. I am using the DG35EC MB with a Core 2 dual CPU.
