Hello!
I have one old disk. It has some hardware fails, but it works. I wanted to change
driver from old ide subsystem (marked as deprecated). My system can't boot
with a new driver because sata subsystem handled this error another way. There is
part dmesg for ide subsystem:

I don't have log, for SATA subsystem, but it tried make initialization after lost interrupt
again and again.
