Thanks for giving it a try. Responses inline.

That is promising news.

This is amd64. I'm still running the 1.4 client on my sparc systems.

It is an hp dl360g6 with 6 gigabytes of memory. The processor is:

unix: [ID 950921 kern.info] cpu7: Intel(r) Xeon(r) CPU           E5530  @ 2.40GHz

$ isainfo -v
64-bit amd64 applications
     vmx sse4.2 sse4.1 ssse3 popcnt tscp cx16 sse3 sse2 sse fxsr mmx cmov 
   amd_sysc cx8 tsc fpu 
32-bit i386 applications
   vmx sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx 
    cmov sep cx8 tsc fpu 

It's a four core processor with hyperthreading so solaris reports it
as 8 virtual processors.

I can't think of anything weird about it. At this point other then
OpenAFS it is still pretty close the basic 151a server install. I did
install Solaris Studio 12.3 to build OpenAFS.

What did you use for your test system? If you used a VM did you
configure it as 64 bit with multiple processors and greater then a
gigabyte of memory (to trigger the 64 bit kernel install.)

Maybe you could email me the kernel module and afsd you used?

Thanks again for taking a look.
