Yes, I saved this output from the 32-bit SMP (non-PAE) HVM when I ran with changeset 14756:

I cannot boot 32-bit SLES10 HVMs, SMP nor PAE, on x86_64 SLES10 xen on Unisys ES7000/one with Intel processors.  I initially tried with HVM memory sizes of 2gb and 16gb, but when I give the HVMs only 512mb, they still do not boot.  I have run both with the ES7000 configured as 8x 32gb and 16x 64gb.  The HVMs either hang in the graphical blue SUSE Linux screen or get this kernel panic: Badness in smp_call_function at arch/i386/kernel/smp.c:595.    

At Keir’s suggestion, I used a binary search method to narrow down changesets, and after building and testing multiple changesets I was able to determine

When you get the ‘Badness in smp_call_function’ message, do you also get a backtrace and/or stack dump?
