Package: linux-image-3.2.0-5-amd64

Version: 3.2.96-3

 

I updated my wheezy kernel because of the meltdown patch.

 

After the update two commands are not working anymore:

 

1.) tw-cli show

2.) smartctl -a -d 3ware,0 /dev/twa0

 

I have a 3ware raid controller with 6 disks and these disks are configured as PVs in my LVM:

The LVM can see the disks behind the raid controller (Model 9500S-8), only the above cli tools are not working anymore.

 

Useful output:

##############

I hope someone can help me to find the cause.

This combination should generally work (and I used it for many years),
but unfortunately the 3w-9xxx driver doesn't support it.

Note that Meltdown has *not* been fixed in 32-bit (i386) kernels.
