Since saturday my fc3+rawhide-updates system started to act strangely. When I boot runlevel 5 or 3 it hangs during the boot process. I can't ctrl-alt-del. It happens with all kernel versions that I have, even "old" ones that worked before saturday, like 2.6.11-1.1240_FC4. If I boot single mode, do a service network start and init 3 I can use the machine ok. Any ideas of what may be wrong ? or even how can I provide more information about it ?
