Hi,
Last year I had a lot of crashes on my linux box.
I experienced hard reset or processes hanged in "D" state forever. It
was much more likely to happen when raid0 array was resyncing.
Yesterday I finally managed to track this problem and it turned out that
it was related to raid10 kernel module.
After applying this patch:
https://lkml.org/lkml/2014/6/4/768
My problems are gone. Today I forced array resync, run kernel kompile
and two VirtualBox machines with heavy I/O load. On arch linux kernel my
machine hanged in 2-3 minutes. Now everything works ok.
Regards,
Łukasz
