[Bug 905832] New: Please backport mmap btrfs fixes/or update to kernel 3.16.7/3.17.3
http://bugzilla.opensuse.org/show_bug.cgi?id=905832 Bug ID: 905832 Summary: Please backport mmap btrfs fixes/or update to kernel 3.16.7/3.17.3 Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: Other OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: hrvoje.senjan@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- we've got big amount of crashes at KDE bugtracker, with each and one being with openSUSE 13.2, using btrfs as root fs and using 3.16.6 kernel. report can be found here: https://bugs.kde.org/show_bug.cgi?id=340657 KSharedDataCache is used for e.g. Plasma cache and icon cache, and it in turn uses posix_fallocate and mmap, thus apparently a btrfs bug triggers crashing (all reports have plasma receiving a SIGBUS) there is also report with very similar usage @ btrfs ML: http://www.spinics.net/lists/linux-btrfs/msg38740.html users there report the issue is gone with 3.17.2 kernels.. (on KDE tracker we have so far one user validating that there is no crashes with 3.17.2) if you have knowledge which would be commit specifically addressing this issue, please backport it, otherwise, if possible, please update to latest stable kernel (i've read the discussion @ opensuse-kernel, so this doesn't look likely ;-) as this is making a KDE experience on openSUSE 13.2 pretty bad. thanks in advance! -- You are receiving this mail because: You are on the CC list for the bug.
