11:34 < Agnar> ffffff4a57090550 cpu, instance #8 (driver not attached)
so I do think it panics while loading cpudrv.
I tried booting off from the current available Solaris 11.4 usb image and that works. So it seems not to be a hardware issue per se.
The CPUs in that system are 4sockets populated XEON X7550 @ 2GHz, 8 cores, HT enabled
I haven't found something comparable in the issue tracker and just want to document the bug here in the slight chance someone sees a solution for this.

15:58 <@rmustacc> Agnar: The useful thing here will be to print the stack trace
again to get the args to trap and printing the struct regs so
we can figure out where we came from. ::cpuinfo might also
help.

Workaround:
it works with -B disable-intel_nhmex=true
set on boot
Updated by Robert Mustacchi over 3 years ago
The intel_nhmex driver has a cousin the intel_nhm driver. Both of these, notably, use smbios to try and get information about the system. The smbios structures evolve over time which is why the smbios routines allow a user to specify a version of the library that they use. This allows us to deal with the fact that the smios flags will change over time. New data is added to the smbios tables and users of the new library will get up to date versions. However, great pain is taken in the library to make sure that we don't break older revisions.
The kernel provides access to smbios, but this isn't part of the DDI. As a result, there is a shared global kernel version of it called ksmbios that uses the version SMB_VERSION to determine which version is in use. Based on the symbol table of intel_nhmex I mostly surmise that it behaves in a similar version to intel_nhm which follows the behavior of other memory controller drivers that use smbios. As part of this, the driver calls smbios_info_memdevice. This would be all well and good, but as part of changes in both 12133 and 10395 which were updates for SMBIOS 3.2 and 3.3, this changed. Normally this would be fine, but this is a closed module which doesn't support anything here.
There is an out, in that we should be able to do actually verify this by disabling the smbios support in the driver We can test that in kmdb and if correct, update the driver.conf file. Thankfully this driver is not load bearing, though it is useful in being able to allow us to enumerate memory faults. Though it's not clear to me how much is different from intel_nhm that we couldn't add logic to that to cover this platform.
Olaf: Would you mind giving this a try in kmdb? I'm mostly doing this by hand so I'm not sure if I'll have 100% of the syntax right. At the initial prompt, run ::bp intel_nhmex`_init this will cause us to break into the system when we load the module. When we hit that, then run nhmex_no_smbios/W 1. If that causes the system to boot just fine, then we can figure out how to deal with this. I suspect by setting the property no-smbios we can deal with this just fine.
