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

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...
