Subject[Regression] sshd hangs on close
DateSat, 30 Aug 2008 09:18:47 +0000 (UTC)
"top" sees multiple instances of:

 6008 root      20 3184 D    0   0:00.06 flush_cpu sshd: root@pts/13            

This is 2.6.27rc5, preemption and tickless turned on, on a 4-CPU machine.
(OK, two hyperthreaded ones :-P) strace() shows that this happens on the
last close of its /dev/ptmx file descriptor, which hangs.

I'll do a bisect early next week unless somebody else identifies a likely
suspect.
