I was installed all pa=D3kages and emulators for my project. I use QEmu for testing the change in the kernel. At first I was installed some change in the driver, for example took ahci, for simulating device error. Then I will find the place in the kernel, wher= e these errors registered. More precisely, kernel gets the CCBs from drivers, with reports about the status of implementation of action with disk devices. The main task of processing these requests is determine the type of error. I think by the end of this week completed the analysis of mistakes and begi= n to implement changes in the kernel for use the ccb from the CAM layer for command iostat.
