I forgot the exact name...please google. noacpi could also help. And enable Magic Sysrq too.... then do complete stack trace of all process. Again, make it as text file and compress it. Remove all non GPL-ed kernel module to avoid your kernel getting tainted. regards, Mulyadi. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
