Message-ID: <bug-76731-13602@https.bugzilla.kernel.org/> Date: Thu, 22 May 2014 14:18:26 +0000 From: bugzilla-daemon@...zilla.kernel.org To: linux-ext4@...r.kernel.org Subject: [Bug 76731] New: WARNING: CPU: 2 PID: 1620 at fs/sysfs/group.c:216 when mounting an external disk https://bugzilla.kernel.org/show_bug.cgi?id=76731 Bug ID: 76731 Summary: WARNING: CPU: 2 PID: 1620 at fs/sysfs/group.c:216 when mounting an external disk Product: File System Version: 2.5 Kernel Version: 3.14 Hardware: i386 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 Assignee: fs_ext4@...nel-bugs.osdl.org Reporter: m.s.tsirkin@...il.com Regression: No I have a disk that I attach through USB. Whenever I attach and kde tries to mount it, I get this warning in dmesg and mount seems to fail. afterwards if I mount from command line, it appears to work fine. the error is probably down to device still spinning up or something, but it does not seem to be handled properly in kernel.
