I bet on a KDE bug here. Attachment 280871 (ps sxa) shows that the processes'
sigmask is set to block the signals. Moreover there are large number of zombie
processes (nepomukserver, kmix, konsole, kopete, ...) which probably means that
their parent is stuck.

Attachment 275715 (sysrq-t of another instance of this issue) shows that many
KDE processes were reparented to init, what means that some crucial process
died.

The problem could also be introduced by the Oracle server running on the host,
but I don't think there is a connection.

Vadim, please provide the output of
ps axouid,pid,ppid,pending,blocked,ignored,caught,stat,tty,time,command
so that we are able to see the process hierarchy along with the signal mask
states. The process should be killable by some of the non-blocked signals like
ILL, ABRT and few others.

Changing component to KDE - oS11.1 + KDE4.2 from Factory. KDE maintainers,
please have a look.
