kernel panic error while updating BIOS and Firmware
 

Hi,
I have IBM x225 server with ServRAID 5i card and is configured RAID 5 with 5 HDDs. We updated the BIOS and Firmware for both System and RAID card.

After we rebooted the machine it is giving following error.

Warning: Adaptor 0 firmware compatible in SB610, but it should be SA510.
Warning: Adaptor 0 compatible version is SB610, but it should be SA510.

Kernel Panic: No init found. Try passing init = option to kernel.

We reinstalled the machine with driver disk but gives same error. We have another IBM machine ( not same model). Created boot disk and was able to boot normally and working fine. But when I am booting from HDD it is not working. I will be very grateful if you can help me out on this.
Cheers,

the new bios isn't for your configuration / the new bios enables some feature in your raid sub and the linux kernel can't handle it this way.
which software have you reinstalled??

be sure the sa610 is known by the kernel. maybe (unlikely) you will have to reinitialize the raidarray some way, as there may be a different layout.
read the changelog from the bios release.
