Just as an update, I'm still looking into this, it's pretty brutal. It
appears to be a bug in the kernel's VT handling code, which is making my

the end of the day, in the meantime just disable rhgb.
Any more details and I'll look into the kernel side as I'm working on
tty and vt locking currently.
Excuse the elementary question...
Would these tty and vt errors in any way be related to some odd behaviour I'm seeing
with the "screen" virtual terminal utility? I'm experiencing some lockups in screen
whenever I do anything particularly "busy". E.g., when doing an update it will
freeze on printing the hashed progress bar. That screen session will hang
completely. Even the SSH escape sequence will not disconnect me. I need to open a
second SSH session and "kill -9" the existing screen sessions.
Unlikely. The rhgb bug looks like it's in the VT code, and has to do
with switching VTs; screen only ever touches pseudoterminals, and
shouldn't be hitting the VT switch code at all.
