Hi, ralf ,  I found that, jiffies remain the same when booting , so
calibrate_delay loop all the time , at while(ticks==jiffies);

I guess it was the problem of timer interrupt as you said.


Someone told me that , it might be the problem of console_init ,but I
still don't know where exactly

the problem is .

Can you tell more about how to fix this ?


Thx
