Subject: arm64: segfaults on next-20170602 with LTP tests
Hi all,
I see that latest and yesterday's linux-next segfaults with tests pth_str01,
pth_str03, rwtest04. Rwtest04 hangs sometimes. Crashes are not always
reproducible. About week ago everything was fine. Kernel log and config file
are attached. The testing is performed on qemu.
Yury
