 All of my problems are still actual on FreeBSD 5.3R, too :-(.
 
 Kernel panics on 'halt -p' always when network cable is connected. When
 network cable is plugged out, there is no panic at all and the laptop
 correctly turns itself off.
 
 Today I have discovered (thanks to pav at FreeBSD.org), that setting
 
 	> ifconfig re0 -txcsum -rxcsum
 
 solves most of my problems. cvsup works ok, no kernel panic on 'halt -p'
 even when the network cable is plugged in. Of course it does not solve
 "rarely hangs at boot", because the setting is applied after boot.
 
 I have not tested the "-txcsum -rxcsum" for long time, just for a few
 hours.
 
 Should I divide this PR (each subproblem into separate PR)?
 
 Other similar problems found:

 Would be great if this could be fixed before 5.4R.
