Description

  • Test a Hermit kernel using GDB and Uhyve's gdbstub functionality, set a breakpoint.
  • Wait. Wait. Wait.
  • Connection is killed and the debugging session is interrupted.

(this was an observation from me and it was also mentioned by @jounathaen, cannot concretely remember how to reproduce or if I missed anything)
