Status I was Running FC3 on a PC platform ( 64 bit Intel P4 Prescott 630 in Foxconn mother board). When I tried to upgrade the FC with rpm I had trouble with my network timing out. Disc is a SATA drive Root file system is LVM I decided to upgrade to FC4. I did a clean install and formatted the disc space. I turned on Samba and few other minor configuration updates. (reinstalled my user directory to get my email back) I did run find from root without any failures. I tried to update with RPM but the network timed out. I am having the same network time outs on my wife's Mac and a new wintel XP laptop. I switched to Yum and the update proceeded smoothly but took 3 hours. Here is where the problems start. I was searching for HelixPlayer to see if it was on the system. Find returned an error " incorrect hard link count in /proc usually a disc driver problem" I decided to reboot to see if the disc would run FSCK. The boot process hung at the same place 2 starting network loopback I stopped the boot the next time and reverted to the old kernel believing that the disc drivers are in the kernel. (June FC4 install discs ) This worked and the system boots. Appears to be fully functional. I tried a "find" and got the same file system error in /proc directory. So I thought I would check if this is a known problem. I assume next steps would be to run FSCK on root disc. ( I do not have experience with LVM and FSCK) I would like any advice on trouble shooting which update is causing the problems. I wanted the FC4-64bit see if there was a performance difference. I can go back and reinstall FC and manage the Yum update more tightly.
