Thanx for all the replies and facts . Actually my main concern is
regarding identifying kernel panics and system hangs
on embedded arm targets where i have access to only one serial port
used primarily for reporting debug messages .

Also wrt  x86 , i tried to use  gdb - kgdb interface using 2 PCs , but
communication used to break too often  .

Then i tried ftrace which i found quite convinient to use on x86 till
now except sometimes when  ftrace takes too much time to print
complete trace on console  in case of crash .

Can crash utility be used for arm targets as well ?
