I was trying to reproduce the corruption that has been reported on the
linux-kernel list by:

Interestingly enough now that I search the archives a similar
corruption was reported last June however 'm.lord' thought it might be a
IDE problem, I don't have any IDE drives on my system.

I have 4 linux systems configured in a 'beowulf'esqe fashion (not
running the beowulf software just yet) which I've been using pretty
much without incident with 2.0.30 (only problem with kernel memory
leaks) for over 6 months. After reading about the 2.0.33 lockup
problems etc. I thought I would try to check some of them out.
I setup one of my systems, clotho, as a 2.0.33 system. My testing so
far consists of running 16 'ttcp' processes as listeners on
clotho. Starting 16 'ttcp' sending processes './ttcp -t -l8192
-n6553600 -p50nn' on another system, and then starting a set of ftp
transfers on clotho, md5sum'ing the result of a 4MB file download, and
looping back and doing it again. With the 'CONFIG_SKB_LARGE' option
set to 'y' I will get the 'Aiee' message within a couple of minutes,
without it set I have run the test for more than 8 hours with only one
strange message: 'NFS silly_rename cleanup failed (err = 2)' (the
/home drive is NFS mounted from my control system).
Here is the relevant part of the .config which fails:

Straight RedHat 4.2 install except the linux kernel 2.0.33, obtained
from ftp.kernel.org and installed.
This system has been very stable with over 100 days uptime with
kernel version 2.0.30 (last reboot was because of kernel memory
leaks). I took it down to try to reproduce some reported problems
with 2.0.33.
If anyone needs any other information let me know.
Regards,
William.
