Patch Set #8, Line 21: uart8250,io,0x3f8
you really do not want to hard the port here.
I think it should be:
console=ttyS0,57600n1.
Also: on SonoraPass we have 2 useful SIO ports: com1 that is wired to debug header and com2 that is wired to SOL. this should be noted int the comment below.
Patch Set #8, Line 21: earlyprintk=uart8250,io,0x3f8
please note: this syntax is not correct. This is extremely confusing, and must be fixed. Since earlyprintk is not specified correctly and under certain conditions kernel might crash before regular console becomes operational, this is really ugly problem.
what we want instead is:
earlyprintk=serial,0x3f8,57600n1
Another option:
earlyprintk=serial,ttyS0,57600n1
which is better.
