I've been having a persistent problem of my text TTYs-- TTYs 1 through 6-- becoming frozen after a short amount of time after the OS has loaded-- within 10 minutes or less. My graphic TTY continues to function as normal, but all six of my text TTYs will freeze and become unresponsive. I have noticed that this problem only occurs when I run a 4.4 kernel. I had built and installed the kernel version 4.4 shortly after it became stable, and had this issue, so I figured it was probably because the new kernel version had only just been released and would still have bugs, so I went back to booting with the 4.3.3 kernel. Today I compiled & installed Linux 4.4.2, and the same problem is occurring. I did not make any radical changes to kernel configuration.. has anyone else experienced anything like this with the 4.4 kernel?
My distribution is Linux Mint Debian edition. Any input would be very much appreciated . I am still fairly new to Linux.
How are your TTY's setup? Using the older method or devpts? What do your logs say? I am running 4.4.4 and haven't such a problem. My fstab regarding TTY's:
Have you solved this problem? I have been confused by the same problem for more than a month, and now I switch to 4.1.19-lts kernel and everything goes well...I really want to know want actually happened when I run 4.4.x kernel...
I've experienced the same issue too after I updated kernel from 4.3.0 to 4.4.0. After some googling I found something interesting in /var/log/Xorg.0.log just right after freezing:

Seems that it's the graphic card driver who is to blame...
My lspci shows:
Did you have to reboot and then looked at /var/log/Xorg.0.log? I have to reboot, it's the only way to get out of the frozen screen. I wrote a bug report with kernel bugzilla. https://bugzilla.kernel.org/show_bug.cgi?id=116541
Does anyone have a fix for this?
I assumed it was a kernel issue. I can add this information to it, if need be.
I found someone else had the similar issue too (https://lists.debian.org/debian-user.../msg00024.html). My text ttys (tty1-6 and tty12) froze but tty7 (X) still worked.
Anyway, I've updated to 4.5.0 and the computer has been running for 2 weeks. Everything goes well now.
