Kernel panic - not syncing: Attempted to kill init!

Hello Red Hat,

could you please help us with this install issue?

When installing F11 Beta in a js12 blade machine, anaconda crashes with "Unable to mount filesystem"
error. Then, during the reboot, a kernel panic occurs. However, I'm not sure if both problems are
related.

It might be important to mention another kernel oops occurs during the boot (see attached dmesg
output). This first oops, related to ehea driver, was already reported on RH Bugzilla #487712 (LTC
Bugzilla #51514), where patches that fix this problem were already submitted.

Besides dmesg, anaconda log from before reboot is also attached.

Please let us know in case you need any additional info.

Thanks.
