Host sometimes misses the EE RDDM during kernel panic causing
RDDM failure. Increase RDDM timeout to overcome this issue.

If we are in the middle of a Linux kernel panic, the host is going down, so why do we care about RDDM?

How did you determine the new value?

Really seems like significantly more detail is needed here.

If kernel panic was due to mhi, we need to have the RDDM dump and this is already supported in upstream MHI.
