Hi David > I wanted to follow-up on this thread since we, too, are seeing issues with GDB and > v4.9-rt kernels. We've been working on upgrading our systems/application from the > v3.18-rt kernel series (specifically v3.18..29-rt30) to v4.9-rt (specifically 4.9.13-rt11) > and immediately started experiencing various GDB related issues. The first (inability > to pause at breakpoints and single-step) was eliminated by reverting to using GDB > v7.11.1 (from GDB v7.12.1). However, the second (the SIGSTOP issue originally > reported by Mathias) isn't something we've been able to work around. Have either of > you made any of your own progress on this issue? Are others also seeing this? No progress from our side... We are staying on the 3.18 kernel (which is not really fine as it is now EOL....)
