panic_print= Bitmask for printing system info when panic happens.
User can chose combination of the following bits:
bit 0: print all tasks info
bit 1: print system memory info
bit 2: print timer info
bit 3: print locks info if CONFIG_LOCKDEP is on
bit 4: print ftrace buffer
bit 5: print all printk messages in buffer
bit 6: print all CPUs backtrace (if available in the arch)
*Be aware* that this option may print a _lot_ of lines,

Use this option carefully, maybe worth to setup a
bigger log buffer with "log_buf_len" along with this.
