Ooops on with 2.4.22 when using rsync over ssh

Ooops on with 2.4.22 when using rsync over ssh

[Emmanuel Mogenet]

The raw and ksymoops'ed oops are at the end of this message.

It happens with a Fedora install and it is 100% reproducible
with my config (happens every single time I launch the rsync command below).

The exact version of the kernel it happens with is:

Linux version 2.4.22-1.2174.nptl (bhcompile@tweety.devel.redhat.com) (gcc version 3.2.3 20030422 (Red Hat Linux 3.2.3-6)) #1 Wed Feb 18 16:38:32 EST 2004

It happens when I launch the following command from a remote machine:

rsync                                   \
        -v                              \
        -c                              \
        -a                              \
        -e 'ssh -p 2222 -l root'        \
        --stats                         \
        --delete                        \
        --dry-run                       \
        --compress                      \
        --progress                      \
        --numeric-ids                   \
        --no-whole-file                 \
        --no-blocking-io                \
        machine_that_oopses:/data       \
        /v/backup/data                  \
