Hi Jorge,

In the 1.4.1.1 release, the scheduler of each thread is set to the
thread itself.  I haven't been able to reproduce the behaviour you're
describing.  For example:

=== L_timer == TCB: e0006c00 == ID: 000d8001 = 01200100/f016e000 == PRIO: 0x64 ===
UIP: 00f20891   queues: Rswl      space: f01303e4/4
USP: 0022fcf0   tstate: RUNNING   ready: L_timer :L_timer    pdir : f016c000
sndhd : NIL_THRD  send : NIL_THRD:NIL_THRD   pager: 000c4001
total quant:    0x0 us, ts length  :       0x2710 us, curr ts: 0x1f6f us
resources:    00000000 []
continuation: f0106440   preemption_cont: 00000000
scheduler: 000d8001    exception_handler: 000c4001
  partner: 000d4001        saved partner: NIL_THRD      saved state: ABORTED

Have you made any modifications that might be causing the problem?
