Hi Mike,

run0 is a external edimax usb device. Page fault occurs when
netstart/dhclient is being processed. Boot up without this network
device installed, insert device and manually sh /etc/netstart throws
out a page fault.

This can happen 2/3 times then finally, whilst performing the above
process, I am able to successfully bring up the device.

Reading uvm man page on a Friday night, I should have a beer instead ...

How about a ddb trace?

PS - if it helps, I hate Lenovo - 2 dead keyboards, 2 dead disks, a
BCM4315 and a poor bios

1. Just a quick note, has anyone else experienced a page fault when
using a Ralink adapter at either bootup or when running netstat?
Seems to be temperamental.

2. Throwing it out to the masses, what's the best login and net fs
provision? (No-to NFS!!!)

:)

What makes you think this has anything to do at all with Ralink?
