--- Comment #2 from Pedro Alves <palves at redhat dot com> ---
I won't be able to look at this myself in the near future, sorry.
The comments in the commit itself should provide hints:
https://sourceware.org/ml/gdb-patches/2015-02/msg00731.html
as well as the series intro:
https://sourceware.org/ml/gdb-patches/2015-02/msg00726.html
See also these later fixes for MIPS:
https://sourceware.org/ml/gdb-patches/2016-02/msg00734.html
https://sourceware.org/ml/gdb-patches/2016-02/msg00762.html
basically, the MIPS kernel didn't report si_code correctly.
Likely Alpha has some similar issue.
"set debug infrun 1" and "set debug lin-lwp 1" will likely show what kind of
loop gdb is stuck in.
