Hi all, I am getting the following prints when I use dmesg command. Why is this happening and what could be the reason for bad block occuring other than power failure during write operation ? Any clues or suggestions appreciated. Thanks, Chandru. mombasa:~# dmesg Linux version 2.4.19-rmk4(v2_13-cvs) (root@chandu) (gcc version 2.95.3 20010315 (release)) #7 Fri Dec 16 21:04:16 IST 2005 CPU: ARM/MINDSPEED Arm920Tid(wb) revision 0 Machine: ARM-Chagall Ignoring unrecognised tag 0x00000000 On node 0 totalpages: 8175 zone(0): 8175 pages. zone(1): 0 pages. zone(2): 0 pages.
