I'm using a Raspberry 4b... seems like there was a change recently in that area?

I don't have any arm64 hardware to reproduce this error, however maybe the following patch will fix it. Could you try it?

Lock on package SB-VM violated when interning EA while in package COMMON-LISP-USER. [Condition of type PACKAGE-LOCKED-ERROR] See also: SBCL Manual, Package Locks [:node]

That seems to be the issue but I don't know what the proper resolution is. Interning and exporting a symbol from a locked package throws an error I think.

I can get around it by causing the package-locked-error for 'sb-vm::ea and picking the continue restart to ignore the package lock for that operation. Then the symbol is already interned and I am able to load ironclad.

I pushed a fix (f215e183e7fe0b66da009c07d70e6f738ea1da03) that should make the SB-VM package lock error disappear.

@glv2 It also fixes same error on ppc64le.
