[Crash-utility] kernel 3.6.10

Hi,

I tried the latest crash tool 6.1.1 (built from sources) on a kernel
3.6.10 dump and it failed while reading the module information.
Error says:
crash: invalid structure member offset: module_core_size
       FILE: kernel.c  LINE: 2974  FUNCTION: module_init()

[../../crash-6.1.1/crash] error trace: 809afc6 => 810ecab => 8152543 =>
80929f9

  80929f9: OFFSET_verify.part.27+71
  8152543: OFFSET_verify+51
  810ecab: module_init+939
  809afc6: main_loop+214

Even if I disable the the modules information gathering (--no_modules)
it fails later on while trying to read the idle tasks:
crash: cannot determine idle task addresses from init_tasks[] or runqueues[]

crash: cannot resolve "init_task_union"

Is this a known issue? Any plans to support kernel 3.6.10?

As a FYI, I can use --minimal to enter the system and retrieve the dmesg
buffer at the crash point.

Thanks,
Pablo Sole.
