I also experienced regular hangs with my P4 (pre-HTT and no SMP in
kernel) after the most recent sched_ule/preemption changes. These were
hard locks and I was unable to ssh in or break to debugger via
Ctrl-Alt-Esc. I backed out revision 1.114 of sched_ule.c and the
machine has been stable since. I don't have a serial console setup on
this machine as my other machines are headless, but I can set that up if
need be. Off hand, the workload on the machine at the time was KDE,
Firefox, Thunderbird, Gaim, several Konsoles, and gkrellm using an
NFS-mounted home directory.
Note that this is with ACPI and without WITNESS or INVARIANTS in the
kernel. Also, my NFS server is an SMP machine and has no problems with
the latest sched_ule.c.
