           Summary: kernel BUG at fs/ext4/inode.c:3123
           Product: File System
           Version: 2.5
    Kernel Version: 2.6.30-rc6
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@...nel-bugs.osdl.org
        ReportedBy: ckom26@...il.com
        Regression: No

Being haunted by a consistent bug in 2.6.29.[234] that kept pdflush stuck at
100% cpu, I fetched and compiled 2.6.30-rc6. Now, I keep getting "kernel BUG at
fs/ext4/inode.c:3123!" (usually when I fire up ktorrent). In the attached
kernel logs you can see 2 different occurences of the bug.

A nearby single core cpu, low end box has not exhibited a single bug or
corruption for 3 months now, since I've converted to ext4, so I tried the
"nosmp" kernel boot parameter on the dual core laptop in question. Lo and
behold, the bug didn't rear its ugly head.

All partitions are mounted with "nodelalloc".
