    Another Kernel Panic Thread - need help!! Bad EIP Value? Need help


    Hi all,

    After a power cut last night my linux server won't boot from it's disk. I have successully booted it from the network though, and can view the filesystems. I ran an fdisk on the partitions and it appeared to come back ok (but was VERY quick). The kernel displays this just before it panics:

    Code:
    md: Autodetecting RAID arrays.
    Unable to handle kernel paging request at virtual address 6f6c622f
     printing eip:
    6f6c622f
    *pde = 00000000

    Can anyone suggest where I should even start looking? I've trawled google and more 'kernel panic analysis' pages than you can shake a stick at, but to no avail. Really hope someone can help, or at least suggest where to start looking.

    Thanks in advance

    it looks like memory allocation problem to me, 6f6c622f is a user space address..
    it looks like swapper proces was running, ad searching for a page on disk for virtual address 6f6c622f...
    but somehow it could not load the page, there may be a problem with page table entry or page corrupt...
    I can not identify call trace..how it went...
    also EFLAGS and other general register values could be observed..
    I am new to kernel, please dont rely on this info, but this is my opinion..
    be if you find the problem you can also let me know...
