[snip more syslog eth1 link down messages] There's really not much information to even start guessing. Here are some tips you can try: - test your RAM (memtest) - try a newer kernel (e.g. from backports) - check temperatures (CPU, case, etc.) - fsck all partitions - check and/or replace if possible the power source of the server - make sure you have all necessary firmware installed (check output of 'dmesg | grep firmware') To receive further help from this list you could: - attach full output of 'dmesg' immediately after a successful boot (run 'dmesg > dmesg.txt' and attach 'dmesg.txt') - upload somewhere a picture of the screen with the kernel panic Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser Offtopic discussions among Debian users and developers: http://lists.alioth.debian.org/mailman/listinfo/d-community-offtopic http://nuvreauspam.ro/gpg-transition.txt
