With MSI and libata DEBUG turned off I had a crash - solid one, SysRQ 
doesn't work. I have forgotten to set console to serial port when 
booting this kernel, so what follows is what I had on the screen, 
hopefully without any typos (and without the initial addresses):

This was a SMP kernel running on an Intel PIV with HyperThreading and 
with 2 disks attached to the controller. I'll try to get this crash 
again with serial console...
