CentOS boot error

Hello guys,

I installed older kernel ( 2.6.28 ) from sources under CentOS 6.4 (2.6.32). During boot process of kernel 2.6.28 I get an error (please take a look at the attachment).

Can you please advice how to make system boot properly ?
thank you

Did you also downgrade all of your system libraries and applications? All RHEL systems from 6.0 on are using the 2.6.32 kernel tree. Trying to install one like 2.6.28 will likely have some serious incompatibilities. What happens when you select the newer kernels from the grub menu?

No, i did not downgrade and libs or apps.

If i choose 2.6.32 kernel, there are no problems with boot process.

If I boot 2.6.28 with "fastboot" option, there are no problems during the boot process. But I would like to have fs check.

You have ext4 file systems. I'm not sure that the older kernel supports it. Have you tried to downgrade the file systems to ext3? They are both based upon ext2, but have journaling (reliability) enhancements. There are differences in the details and performance (under some situations). The file system structure is the same, which is why the /sbin/e2fsck tool works on all of ext2/3/4 file systems.
