http://bugzilla.kernel.org/show_bug.cgi?id=15349 Summary: kernel BUG at fs/ext4/inode.c:1853! Product: File System Version: 2.5 Kernel Version: Linux muser 2.6.31.12-desktop-1mnb #1 SMP Tue Jan 26 03:35:36 EST 2010 i686 Pentium(R) Dual-Core CPU E6500 @ 2.93GHz GNU/Linux Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 AssignedTo: fs_ext4@xxxxxxxxxxxxxxxxxxxx ReportedBy: bas@xxxxxxxx Regression: No Hello! Here is a bug report. The hard drive subsystem was heavily used by IO operations (torrent), at the same time I was unraring an archive. After this problem happened, load average started increasing dramatically, and the system became unresponsive. Processes couldn't be killed, system couldn't even be rebooted. So i had to reset it manually. Feb 18 22:30:33 muser klogd: ------------[ cut here ]------------ Feb 18 22:30:33 muser klogd: kernel BUG at fs/ext4/inode.c:1853!
