I have a very busy webserver. Around 2 weeks ago i upgraded from 2.2.18 to 2.4.2-ac20 (SCSI-System, 512 MB RAM, 3 SCSI-Disks, P-III-500). Everything worked fine, the 2.4x Kernel boosted the box a lot :) But suddenly the box was offline. One technical assistant from our ISP tried to reboot our server (he couldn't tell me if there had been any messages on the screen), but the system always hangs on Freeing unused kernel memory: xxk freed So we took the box home and tried to boot it from a bootdisk (generated as we installed the box, redhat 7.0). The SAME problem occurs ... Freeing unused kernel memory: xxk freed The system hangs (i've tried 2.2.18 AND 2.4.2-ac20, 2.2.16 is on our bootdisk). I thought it could be the swap-partition ... so we inserted an IDE Disk, installed a small system so that i was able to mount the SCSI-Disks. So i rebuild the swap-parition with mkswap /dev/sda5 and activated it via swapon /dev/sda5 ... worked. So i tried to boot it again from the SCSI-Disks ... nothing! The same odd failure ... I've never hat such Problems before .. we've already changed every piece of hardware that's been in the box (except the disks, but theire looking ok because i can mount them and run e2fsck over it :) ) I need help, because we're already down for 3 Days now. What causes the system to hang at this point?? What must i do the be able to boot the system from the scsi-disks again?
