yes, it was having old modules, after deleting old modules.

[root@...v5 linux-2.6-tip]# make modules_install
  INSTALL arch/x86/kernel/test_nx.ko
  INSTALL drivers/hid/hid-dummy.ko
  INSTALL drivers/scsi/scsi_wait_scan.ko
  DEPMOD  2.6.29-rc8-tip
[root@...v5 jaswinder-git]# /sbin/mkinitrd /boot/initrd-2.6-tip.img 2.6.29-rc8-tip
[root@...v5 linux-2.6-tip]#


By following above steps, I get rid of oops, and here is my lsmod:
[jaswinder@...v5]$ /sbin/lsmod 
Module                  Size  Used by
[jaswinder@...v5]$
