I don't think this was the problem we had, although this may have been 
fixed also. I don't have a serial port on this box, so I can't test with 
my kernel.

The problem that affected 3.4 kernels apparently had something to do 
with something called spinlock or some such. It caused Speakup to lock 
the entire system whenever a speakup-related key on the numeric keypad 
was pressed. It didn't affect keypadless laptops, only desktops and 
laptops with the numeric keypad. This is the bug that was fixed in the 
3.6 kernel tree, although I believe a patch may have been submitted for 
serial synths as well. Not sure though.
