Has anybordy else seen corruption of the output from SMC1 when used as serial console?
This only occurs in in 2.6.8 and later (when the CPM serial drivers got moved)
And it only occurs when init is writing to screen. 2.6.7 and earlier works perfectly.
It happens at all baudrates tested (9600 and 115200)

Anybody seen something similar and/or have a clue where to start looking for this?
I have looked at the serial drivers, and cannot find any differences large differences from whenthey still were in arch/ppc/8260_io to the ones in drivers/serial/cpm_uart


Freeing unused kernel memory: 288k iεt
I■T: version 2.85 boot∙g
I■T Entering runlevel: 3

These lines are the only ones that get corrupted. All other output (kernel printouts, console and startup scripts) are normal.
