Não Terminal TTY após atualização e reinicialização do Kernel CENTOS

Question

tem um VPS e recentemente eu instalei um novo kernel

Depois que eu reiniciei, tentei fazer o login pelo SSH e recebi esta mensagem:

PTY allocation request failed on channel 0

Depois de algumas pesquisas, descobrimos que, usando esse código, o login acontece, mas com erros:

# ssh -v -T root@server /bin/bash -i

Então ... alguma sugestão? Alguém falou sobre /etc/resolv.conf , mas mesmo que eu mude e reinicie, o arquivo original é substituído.

Mas basicamente o terminal não está funcionando.

Comentário: tentei -ttt , mas sem sorte:

$ ssh -ttt root@server
PTY allocation request failed on channel 0
