No, I don't have CONFIG_LEGACY_PTYs. I do have UNIX98 PTYs, and I tried enabling alternate namespaces, but that didn't help either. > > Also related, if you have LEGACY_PTYS: > > "LEGACY_PTY_COUNT: > > The maximum number of legacy PTYs that can be used at any one time. > The default is 256, and should be more than enough.

Yeah, I'm not using CONFIG_LEGACY_PTY, so LEGACY_PTY_COUNT doesn't even make itself available in menuconfig. -- :wq
