Both yes and early work fine.
However when I set IUCODE_TOOL_INITRAMFS=no, update the initramfs, reboot and
then reinstall intel-microcode I get the same trap invalid opcode.
I guess no processes that use libpthread run during early boot when the
microcode update is applied.

Thank you. That helps immensely!
At least now we have an easy possible workaround: blacklist a few cpuids in
the package postinst from a runtime update, or drop runtime update entirely
and always require a reboot.
However
It looks like this is the microcode update that disables TSX where it is broken.
The hle flag is removed from cpuinfo flags (see attached cpuinfo files).

I thought as much.
Also, let me guess: if you update in IUCODE_TOOL_INITRAMFS=yes, the hle
flag
