Hi all,

installed the Snapshot from the 27th on this shiny new Inspiron 8600 
Laptop and it panics under network-load. cvsuped at the 29th, but the 
problem persists. /usr/ports/ is mounted via NFS from a 5.2.1R Server 
and the laptop panics when doing a 'make install' in x11/xorg. More 
specifically, it panics while 'make extract'

Here's the manuscript of the trace, somehow I'm unable to get a crash 
dump...

panic: bfe_start: attempted use of a free mbuf!

A bootverbose dmesg can be found here [1]. There are some other strange 
things with this laptop. First of all, three USB Ports get detected, 
while there are only two ports on the backside  (internal USB port??). 
And the DVD+RW drive only gets detected sporadically.
