the command:
time tar -kxjf linux-2.4.4-2002_12_04.tar.bz2 2>&1 |
cat > /dev/null

needs about 30 seconds with kernel 2.4.25

tar gives warnings if the file already exists to stderr so I
pipe it through cat to delete the error messages

If I use this command the second time with kernel
2.4.22-openmosix3smp then it hangs endless and ps -
afx shows that all processes are wait_s

if anybody can help me...

thanks

    What happens when you do just "bunzip2 file"? BTW, where
    did you get this file? and what is it?

    linux-2.4.4-2002_12_04.tar.bz2 is a tarred collection of
    source files which is bzipped.
    These files are needed to build embedded linux version 2.4.4
    from 04.12.2002.
    It is an automated build getting the sourcetree to the
    destination directories and crosscompile them.
    If the files already exist, there are a lot of error
    messages generated by tar which I want to throw away.
    I have done this with an openmosix cluster 2.4.18 without
    problems. Now I want to migrate the cluster from Redhat 7.3
    to Redhat 9.0 and use openmosixkernel 2.4.25 but this kernel
    isn't available yet, so I thought I can use openmosixkernel
    2.4.22-2 or openmosix-2.4.22-3smp (the machines are double
    XEONs)
    The problem seems to be a starvation-problem. If it occurs
    then the command ps axf shows that all processes are wait_s
    and I don't know what this means....
