SSH terminal hangs (tty_ldisc_hangup)

  • 772

The SSH console is timing out and I'm not able to execute any commands.

I've noticed that I can execute commands remotely but when I try to allocate TTY it hangs:

Works:

$ ssh [email protected] "uname -a"
Linux example.com 2.6.32-504.el6.x86_64 #1 SMP Tue Sep 16 01:56:35 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux

Hangs:

$ ssh -t [email protected] "uname -a"
$ ssh [email protected] "dmesg"
tty_ldisc_hangup: waiting (sshd) for pts1 took too long, but we keep waiting...

    It looks like the problem was related to hpsa module shipped with kernel kernel-2.6.32-504.el6.x86_64.
