(09/22/2010) Today, I brushed up The best of 11 kernel panic message (google indexed order) PANIC MESSAGE Index (Type) Kernel Panic Message in the world ======================================================================= 58,300.(A)Kernel panic - not syncing: VFS: Unable to mount root fs on 47,900.(B)kernel panic - not syncing: Attempted to kill init! 28,900.(C)Kernel panic - not syncing: Aiee, killing interrupt handler! 15,600.(D)kernel panic - not syncing: Fatal exception in interrupt. 12,300.(E)Kernel panic - not syncing: No init found, Try passing init= option to kernel 6,930.(F)Kernel panic - not syncing: Out of memory and no killable processes.. 4,900.(G)Kernel panic - not syncing: CPU context corrupt 3,700.(H)Kernel panic - not syncing: Oops 1,520.(I)Kernel panic - not syncing: IO-APIC + timer doesn't work! 1,230.(J)Kernel panic - not syncing: Machine check 110.(K)Kernel panic - not syncing: nmi watchdog Did you see whole message? I have classified these message by reason&solution. REASON Message Type ============================= Hardware :G,I,J,K Software Configuration:A,B,E,F,H,(maybe caused by Hardware) Software Bug :C,D,(maybe caused by Software config&Hardware) SOLUTION REASON SOLUTION ============================= Hardware :Replace New Hardware Software Configuration:Back to old configuration. Software Bug :Do not use this feature. Do not make these condition. Ask someone to fix this problem. Please comment about reason & solution by each message.(A-K) (This Support schemes are oriented by only CentOS ) (Maybe raw wild Linux(Debian) ignores this solution because they are more unstable.) I wish this table will help someone to against CentOS kernel trouble... The centos.org has many trouble topics with "Kernel panic". You can search "panic message" in CentOS forum. (This is Ad for yahoogroups) https://www.centos.org/modules/newbb/index.php Don't ask about other distribution(Debian, Ubuntu, fedora) on CentOS's ML&forum Thanks. Tsuyoshi.
