pls help me.
First, spell our your words, please.
Second, if you're using RedHat enterprise, THEY will analyze the core dump for you, since you're paying for support from them.
You can use the vbcode tags to make your post easier to read. The code tags are at the top of the reply window, either # (code) or balloon (left of #) for Quote.
As for the error, it looks like the panic is due to the settling of the storage media therefore not available to the kernel. As stated by 'TBone', you should use RH for diagnosis of the problem since you paid for it.

Thanx for reply.
Unfortunately we dont have a agreement with RedHat.So i am not in position to ask help from them...we have another 2 servers connected to EMC in primary site.there also we used RHEL 5.1 but kernel was Xen.Not PAE
So i was thinking is there any problem with PAE kernel.
I had boot problems using the 2.6.27.29-0.1-pae kernel. The system would hang "Waiting for /dev/disk-by-id...". I resolved this by installing kernel 2.6.27.29-0.1-default and haven't had this problem since.

Is there any way to update PAE kernel to Xen
I don't use RH for the reason of fragmenting and commercialization of the Linux. The 'PAE' will gain you large memory. As for 'XEN' that will be dictated by the hardware that you currently have as to whether there will be limitations.
I suggest that you do a little google or wiki on "PAE' and 'XEN' to get more information.
