weird hangs with 26oct current and releng_6_0

[KubaTyszko]

hi everyone

i had current as of about august, yesterday i upgraded to latest
current and:
- it did crash sometimes just after running pppoe connection (never
happened on earlier -current)
- when i try to run startx it does nothing, but when i ctrl+c and run
startx again few times it finally runs fine.
the same happens with RELENG_6_0

maybe some of you did have similar problems ?
