I enclose an unsorted file for some of the log entries posted previously 
from /var/log/messages. This shows that the stream of kernel messages can be 
up to a minute or more out of sync with the other messages. I have looked at 
the log quite carefully and I think that the timestamps are correct, and it 
was correct to sort the file to get the true sequence of events. I do not 
think that the time differences are caused by time synchronisation (ntpd) 
because that would affect all messages equally after that service was 
started. This out-of-sequence effect is most notable at boot and while there 
are many debug messages going to the logs (I left out many of the messages 
which were not relevant). It may be something to do with the fact that there 
is a separate mechanism for kernel messages (klogd) and that syslog does not 
start until S12 which is after kudzu, iptables and network etc. and so could 
there be a backlog of messages to be written to the log? Perhaps someone can 
throw more light on this.

I agree that it is difficult to understand what is happening with hotplug 
and the loading of the prism2_usb module, but I think that the log I posted 
was valid.
