I'm answering to it myself - because the cd is mounted at install time. If 
I mount it in the working system, interrupt storm stops as well. Isn't 
there something low level annoying (probing?) the device if it isn't 
mounted and it's not aligigning requests correctly (AFAIR SATA ATAPI 
required requests being multiple of 4 (?) bytes)?
