    [PATCH] ub: fix for blank CDs · 1872bceb
    Pete Zaitcev authored
    This patch fixes a microcode lockup in my CD-ROM adapters when a blank CD
    is inserted.  However, do not try to burn CDs yet!  I'm pretty sure that
    trying it will end in coasters.
    
     - Fix a few cases where we were unable to resynchronize with replies
       for previous commands. The main thing is to keep reading replies
       in case of a stall. This is done with the new state CLRRS.
     - Since I am forgetting the basic state machine already, document it.
     - Move counter increments in the looping path in its own function.
     - Fix a harmless buglet in case CSW read fails to submit: do not
       override state.
     - Implement the Alan Stern's idea for adaptive signature checking.
