problems with -current

dear hackers,

after cvsup'ing recent current (as of yesterday evening pst) and 
building/installing new kernel/world i started having problems:

problem 1: startx simply reboots my laptop. i can see x coming up, then 
after just a few seconds my laptop reboots. no window manager, no 
nothing. my laptop is a dell with some radeon video card. will provide 
more details on request.

problem 2: when system is booted and filesystem is not clean fsck is 
started and checks all dirty filesystems. then boot process continues as 
usual, however root filesystem is still mounted read-only, i.e.

--->  /dev/ad0s1a on / (ufs, local, read-only)  <---
devfs on /dev (devfs, local)
/dev/ad0s1d on /tmp (ufs, local, soft-updates)
/dev/ad0s1f on /usr (ufs, local, soft-updates)
/dev/ad0s1e on /var (ufs, local, soft-updates)
linprocfs on /usr/compat/linux/proc (linprocfs, local)
devfs on /var/named/dev (devfs, local)

so, anyone sees this as well or its just me.

thanks,
max
