Hi!
Just installed 4.9-RELEASE with jailed sshd over a null-mounted (bin,
dev,etc,usr)
dirs crashing. It's an IBM xSeries 345 with SMP with HT. (dmesg at the end)
The only one thing configured is a multi-VLAN interface. In the jail's dev
there was
MAKEDEV jail. The last debug msg from sshd is: Allocating pty.
The crash also happen with non-SMP kernel. The same things was OK on 4.8.
The same way jailed other services (bind, djbdns, oops, ...) works fine.
What else i should debug or what to show? Any idea what wrong I do?
KJ.
the kernel msg:
