Lose response when shutdown or logoff & tty can't login

Hello

When I try to shutdown, reboot, logout, system have a great probability to no response, black screen and sysrq not work.
sometime switch tty also like that.

Determine the high CPU usage from the voice of the fan. hard disk and network useless.

system logs are not useful information:

Feb 29 19:05:25 localhost shutdown[6412]: shutting down for system reboot
Feb 29 19:06:43 localhost kernel: [    0.000000] Initializing cgroup subsys cpuset

logs may no chance to to write.

nvidia 295.20-2
xorg-server 1.11.4-1
gdm 3.2.1.1-1

Another problem:
tty can't login, only show login, no password, like this :

XXXXX login: abcde
jgjteriophjbotr
rhvgtbh mkergr
hbstrhtrshsr

does not prompt for a password, after a few seconds to reset the login screen.
only single-user mode can login.

maybe daemon problem?

Re: Lose response when shutdown or logoff & tty can't login

The TTY login isn't supposed to show the password. This is in case someone is looking over your shoulder or something.

yourhostname login: yourusername
Password: _

You using btrfs for the root drive?

https://btrfs.wiki.kernel.org

"Note that Btrfs does not yet have a fsck tool that can fix errors. While Btrfs is stable on a stable machine, it is currently possible to corrupt a filesystem irrecoverably if your machine crashes or loses power on disks that don't handle flush requests correctly. This will be fixed when the fsck tool is ready."

I have made a personal commitment not to reply in topics that start with a lowercase letter. Proper grammar and punctuation is a sign of respect, and if you do not show any, you will NOT receive any help (at least not from me).

Re: Lose response when shutdown or logoff & tty can't login

only  [ yourhostname login: yourusername ]
without [ Password: ]
looks input as in the buffer.

two weeks ago works well.
use btrfs six months, does not look like it problem.
