Error: Oops: kernel access of bad area, sig: 11

[Aman]

Hi All

Earlier I was getting error "EXT2-fs error (device ramdisk(1,0)):
ext2_check_page: bad entry in directory #20: unaligned directory entry -
offset=0, inode=4294967295, rec_len=65535, name_len=255". Now if I change
the ram size from 8MB to 6MB , I am getting different error. Below is the
console output.

Earlier I used to get an error "Warning: unable to open an initial console."
which is not coming after I changed the ram disk size.

Can anyone help me in solving this issue.

Thanking you in advance
Regards
Aman
