3.0-rc1 problem with usb, cdrom

With 3.0-rc1 have the following problems, on my computer and some laptops:

/ during booting, udev initialization, it stops several times appr. 1 minute (but don't crash)

/ At the beginning, the system behaves normal, but later the usb system don't work at all; then no periferics connected (like: printer, usb key , ...) is recognized with lsusb, and the KDE3 device manager stops to work

/ On mounting a dvd with /mount /dev/sr0 /cdrom , an error messages comes, it dont mount

Below see the syslog. At 13:30, attempt to find sdb ,
is a sucessless attempt to find the usb key (lsusb dont
find it). At 13:33, attempt to mount a dvd.
