Default 5.5 x86_64 live cd

In the bang head and repeat mode here.

The live usb partition is /dev/sda1

Reboot / power on
It auto mounts the /dev/sda2 as ext4 on /mnt/disc/sda2
$ umount /mnt/disc/sda2
$ mkdir /root/foo
$ mke2fs /dev/sda2
$ mount /dev/sda2 /root/foo
Kernel panic

Snip from the kernel panic:
??????
list_del+0xb/0x71
cache_alloc_refill+0xf1/0x186
ext2_fill_super+0x0/0xa37
....
system_call+0x7e/0x83

Default 5.5 x86_64 live cd

A preliminary development version of ext4 was included in version 2.6.19[4]*of the*Linux kernel. On 11 October 2008, the patches that mark ext4 as stable code were merged in the Linux 2.6.28 source code repositories,[5]*denoting the end of the development phase and recommending ext4 adoption. Kernel 2.6.28, containing the ext4 filesystem, was finally released on 25 December
2008

CentOS5.5 has the 2.6.18.* kernel so doesn't support ext4

WRONG - please look at the CentOS/Redhat release notes - it was back
ported - this is why we use this distro.
