Hi I am chasing a problem with my FC4 box. It suddenly hangs up, totally frozen. The mouse does not move, nothing on the monitor changes, even if I ping it, i do not get any answer, the pings come back like it's not there. My system is a Celeron 1.3 Ghz, 512 MB RAM, 30 MB IDE HDD I t used to work fine with FC3, and then it started misbehaving. I thought it was something in FC3 and I upgraded to FC4 but the problem remains. I tested the memory for one full day with Memtest86 without errors, I also changed the CMOS battery, just in case. With Fedora FC3, I had to ifdown eth0 and ifup eth0 to regain network control after freezing up and rebooting. Now with FC4 it recovers network capabilities automatically. Looking forward to a bad HD, I booted with the rescue CD , did not load the filesystem and performed an e2fsck -c on the Hard Disk. It did not complain of any badblocks or any such thing. How can I troubleshoot this? Given that the system freezes up, nothing appears on the logs. Peeking on the message log the most irregular thing I could see was this entry: bloody logrotate: ALERT exited abnormally with [1] but I am not even sure if it is related. I just disassembled another socket 370 system when upgrading towards an AMD64,so I have a full motherboard + 512MB RAM and another processor, but I would rather not start switching components at random, especially motherboards without any clue about what is happening and why. Thanks for any help Javier -- ------------------------------ /\_/\ |O O| pepebuho@xxxxxxxxxxx ~~~~ Javier Perez ~~~~ While the night runs ~~~~ toward the day... m m Pepebuho watches from his high perch.
