I did my kernel update on 24th July and since then I have performance issues (huge delays) with my RAID.
First I suspected SAMBA was causing those delays, but today I noticed same poor performance and delays using Nautilus to browse folders on RAID (accessing it locally on Ubuntu machine, NOT over samba/network).

So.. there might be something related to this kernel update..
I will try to recompile RAID driver, maybe it helps, any ideas why my RAID shows poor performance after latest kernel update?

Please, could someone point me to the right direction, where to start fix it?
Before kernel update everything worked smoothly since installation.

I think this is about my situation (quote from ReadMe):

4) Driver don't work after a kernel upgrade

When you update the kernel to a new version, the pre-compiled driver modules
will no longer work for the new kernel. You have to build new driver for the
new kernel and update the driver at same time. Remember to make a backup of the
old kernel and driver in your boot configuration in case the kernel upgrade.

Can someone guide me how to build new driver and update at the same time? I guess I allowed back-up cration during kernel update process, but not sure where to look for files
