--- Comment #8 from David Sterba ---
I've backported the rest of 3.17.y patches, 3 of them but neither looks related
to this bug. Additionally a few more backports from 3.18.
I went trhough all the reported bugs/duplicates, there's no kernel crash. The
userspace apps get SIGBUS from various library calls. This is above the
filesystem layer and I don't believe it's a btrfs bug, altough it may help to
make it visible under some circumstances.
Analyzing the kde.org bugs, I see a pattern that points to SSE* related
functions:
Last call before the crash (from 341168, 340634, 340651):
Thread 1 (Thread 0x7f98f32ae800 (LWP 20284)):
[KCrash Handler]
#5 0x00007f98f2b1aa0c in __strncmp_ssse3 () at /lib64/libc.so.6
...
bug 340657:
#5 0x00007f54f920c6c9 in __memcpy_sse2_unaligned () at /lib64/libc.so.6
Conclusion, this is not a btrfs bug, but the backport was worth anyway. Please
open a new bug.
