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
 registers/capabilities.

 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.
