Summary0003259: Kernel panic after upgrade to 2.4.1, kernel module mptsas is missing
DescriptionI did an efw-upgrade today from a running 2.3 installation. After reboot the maschine stopped with kernel panic "ERROR opening /dev/console"
I did a fresh installation of version 2.4 RESPIN on the machine, which was running fine. After efw-upgrade and reboot I ran into the same error.

I found a warning in the efw-upgrade process:
Output from kernel-3:
WARNING: No module mptsas found for kernel, continuing anyway

I checked /etc/modprobe.conf which shows:
alias scsi_hostadapter ata_piix
alias eth e1000e
alias scsi_hostadapter mptsas
alias eth tg3

When I run "find / -name mpt*" on the 2.4.0 version I get:

After updating to 2.4.1 I get from "find / -name mpt*"

So I believe the kernel panic is a result of the missing mptsas module in the new kernel release.

I've tested the 2.4.1 ISO, the controller is now detected and the mptsas module is showing up. I've also tested the update process, it installs a mptsas module now.
Thank you!
