[Crash-utility] crash problems with linux-4.5

[Steve Wise]

Hi,

Just forcing a crash dump via 'echo c > /proc/sysrq-trigger' results in a crash
dump that has no tasks saved.  I see _lots_ of these errors when loading the
dump with the latest crash from the git repo:

crash: page excluded: kernel virtual address: ffff88103c5a9000  type:
"fill_task_struct"
WARNING: active task ffff881078a04340 on cpu 3 not found in PID hash

Then nothing is in the dump:

crash> ps
   PID    PPID  CPU       TASK        ST  %MEM     VSZ    RSS  COMM
>     0      0   0  ffffffff81c0f4c0  RU   0.0       0      0  [swapper/0]
crash>

Any ideas?

I'm using top-o-tree from Dave's git repo
https://github.com/crash-utility/crash.git:
