           Summary: slab corruption when mounting ext3
    Kernel Version: 2.5.69
            Status: NEW
          Severity: high
             Owner: [e-mail]
         Submitter: [e-mail]

Distribution: custom
Hardware Environment: Tyan TigerMP with Dual Athlon MP, all SCSI system
Software Environment: gcc 3.2.3, mount mount-2.11z, e2fsprogs 1.32
Problem Description:

I get slab corruption while trying to mount the first partition with a ext3
journal, it doesn't happen when mounting the subsequent ones. It happens on
every boot, sometimes (about 33% of the time) causing mount to segfault and not
mount the other paritions - the rest of the time, it continues to boot normally
