next in thread | raw e-mail | index | archive | help
Is there a tool or approach to listing the order in which SYSINIT's are
executed during boot? I'm currently trying to diagnose a 7.0-CURRENT hang
of a P54C machine just after the WITNESS message is printed. It's obvious
I'm not getting the whole picture here.
