https://bugzilla.kernel.org/show_bug.cgi?id=60786 Bug ID: 60786 Summary: xfstest generic/068 failure - kernel BUG at fs/jbd2/transaction.c:2143! Product: File System Version: 2.5 Kernel Version: 3.11-rc6 Hardware: ARM OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 Assignee: fs_ext4@xxxxxxxxxxxxxxxxxxxx Reporter: enwlinux@xxxxxxxxx Regression: No Created attachment 107296 --> https://bugzilla.kernel.org/attachment.cgi?id=107296&action=edit kernel trace from Pandaboard running 3.11-rc6 Xfstest generic/068 fails roughly 40% of the time when run on a Pandaboard ES (ARM) against a test filesystem mounted with the data=journal option. In this case, an assertion fails in the kernel: "kernel BUG at fs/jbd2/transaction.c:2143!" (full trace attached). This is a long-standing bug which may have become more visible in recent releases; it's now become a notable annoyance during routine regression testing. Recovering from the bug requires rebooting and power-cycling the Pandaboard. The same bug has been seen on x86-64 in previous releases / release candidates, but appears to occur at much lower frequency. It did not occur once in 20 trials on an x86-64 KVM guest configured similarly to the Pandaboard test system running 3.11-rc6 (although another BUG, reported separately, did). It looks like Jan Kara may have made the most recent comments related to this and another similar bug: http://www.spinics.net/lists/linux-ext4/msg36858.html. (Note that the statement currently at line 2143 in transaction.c was at line 1986 in 3.8.) Test system hardware configuration: Pandaboard ES (2 core TI OMAP4 ARM CPU, 1 GB memory) 1 TB Western Digital SATA III disk in USB2-attached external enclosure Test file systems located in three 5.37 GB partitions on USB-attached disk Test system software configuration: Mainline kernel 3.11-rc6 on Ubuntu 12.10 base e2fsprogs, master branch 93061ea0f4d9f94579d09480f17dd47169c82081 xfsprogs, master branch 20526770e76013587c6148fef9e30ac85332fa65 xfstests, master branch 54d6adf7c98500a177f0507c5905ed6dfb2fa888 xfstests-bld, master branch 723c23e1b2756b911dbb50bbd08c0afa5b836e3b -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
