I think this error is related to the one below. I think you just need to
update your kernel.

This one I have not seen before. Do you know what module isgetting
loaded? It might be due to the other block dev error above.
If you are trying to read the module from a iscsi disk, then the problem
is probably that there was a bug in the scsi layer above and you cannot
access the disk due to it, so you get the error below.
If the module was on some local disk, then I am not sure.
I get the following call traces:

Also with fdisk I get:

Unable to open /dev/sda
DebianTemp:~#
Would anybody be able to tell me what's happening?
