Description Patrick Steiner 2008-01-21 02:56:15 EST
i have updated some of our dell poweredge 2950 and poweredge 1950 to

After this i got a kernel panic after boot (no lvm found) switching back to 
2.6.9-55.0.12.ELsmp helps.

so i looked at the to kernel packages an found, that the megaraid_sas kernel
module dont get loaded with the new kernel.

take a look into the init file
diff -ur 55/init 67/init

i noticed that /sbin/mkinitrd doesnt add this module. 

but the megaraid_sas module is loaded (shown with lsmod)
