Re: Hang with isync

No MSR is 00029030 and user mode bit is not set here.

I had missed it in the prev mail:

This is the stack trace.

Registers:
GPR00: 00069030

This is the MSR and it has the user-mode bit set, which is surely wrong.
This is not how one gets to user space.

00048000

The MSR had this or'ed into it, which is setting the user-mode bit.
Surely that's wrong.
