Hi all,
With relatively recent 5.4, I'm seeing hangs that worry me. The box
(dual opteron) accepts keyboard input, but it won't actually DO
anything.. SSHing in gives me a TCP session but no actualy password
prompt. Trying to log in on (serial) console doesn't work, I just get
a newline after entering the username, no password prompt. On SSH
shells alredy open, I can't even get a new prompt line, all I get is
newlines.
But the best part is: The kernel debugger doesn't seem to work. I've
got BREAK_TO_DEBUGGER in my kernel config, but here's what happens:
telnet> send brk
KDB: enter: Line break on console
3KtDhB:a s tpaicdk 1b1a0e00:0
aitd l e _ p r o c ( ) a t i d l e _ p r o c + 0 x 1 1 3

...and then it keeps spewing d's and db's and stuff at me at
whichever speed my serial can handle. In other words, useless. All I
can do at this point is log in to my power switch and powercycle the
box.
Anyone?
