OK, I'll hook up a serconsole tomorrow ..
for now some good old quick n dirty copy paste by pen and paper :
11290 (i486-pc-linux-gnu-gcc]
sched_switch
mi_switch
sleepq_switch
sleepq_wait
_sleep
linux_vfork
ia32_syscall
Xint0x80_syscall
syscall (190, Linux ELF32, linux_vfork)
11291 (cc1)
sched_switch
mi_switch
sleepq_switch
sleepq_catch_signals
sleepq_wait_sig
_sleep
pipe_write
dofilewrite
kern_writev
write
ia32_syscall
Xint80_syscall
syscall (4, Linux ELF32, write)
Thanx for your help.
