I am having a problem with KDB over serial port. These are the steps i follow ....
1] Enter KDB via serial port using Ctrl - A sequence 2] Put breakpoint using bp command [ bp c011b950 (do_fork routine ) ] 3] give a go command. 4] When the breakpoint is hit , the control is passed to the serial console. But after this i am not able to do anything on the serial console. My keyboard/mouse dosen't respond. I can see the KDB prompt , but can't do anything with it. Also this problem is very inconsistent .Some time the hang occurs at the first bp hit and sometime it occurs when the breakpoint hits 7th time. Can the polling routine for serial console be a culprit here .. I am using Redhat 7.3 kernel ( 2.4.18-3 ) on a 2 way IBM x-series 350 SMP machine. This problem seems to be only on SMP machines. Does anyone know about this problem ? Any pointers on this would be helpful ..... -------------------------------------------------------------------- Sachin P Sant Linux Change Team India Software Labs 7B1 Golden Enclave , Airport Road Bangalore , India Ph : 91-80-5044755 Internal : 3755 email : [EMAIL PROTECTED] ---------------------------------------------------------------------
