Comment (by Joel Sherrill):

 Thank you for the very detailed bug report. The person who did the aarch64
 libdebugger port is on holiday so I thought I would ask a couple of
 questions while they were away.

 Is the commit you mentioned from a git bisect or just the random hash you
 were testing against?

 Did you happen to test this with RTEMS build with SMP disabled? I don't
 think that matters here but you never know.

 And were you testing against real hardware or qemu? I don't recall which
 architectures qemu supports enough to even let libdebugger work. Since it
 has its own gdb server, often it does not simulate the needed debug

 If anyone in the community can test this against another architecture, it
 would be appreciated. Since it appears to be locking related, I suspect
 this is an architecture independent failure.
