Problem with kernel upgrade and dmraid (LSI megaraid)

[Andreas Oster]

Hello Luca,

sorry for the delay, but I have been busy lately and did not find
the time to create the log you asked for.

Attached you´ll find the startup output until it reaches the
kernel panic.

I really hope you can find the cause of this issue :-)


kind regards

Andreas
