Re: [Crash-utility] crash problems with linux-4.5
----- Original Message -----
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

If you have configured kdump to use makedumpfile -d31, it is probably this:
[Crash-utility] makedumpfile: 4.5 kernel commit breaks page filtering

PS: I'm not on the crash-utility list, so please include my email
in any
replies.
PS: if you're using crash on bleeding edge kernels, you might want to join
the list, at least in digest mode.
