I'm not sure it's good. I loose my file system :
After one RT test, I cannot ls -l on all my filesystems :
# ls -l
ls: get_cpu_speed.c: Input/output error
ls: get_cpu_speed.o: Input/output error
ls: toto: Input/output error
ls: fonctions.h: Input/output error
ls: Makefile: Input/output error
ls: max_tsc_aff.c: Input/output error
ls: max_tsc_aff.o: Input/output error
total 12
