ML370 G3 lockup with RH2.1

[jpj]

Hi all,
This has been posted on proliant servers ML ...
We have ML370 G3 system wich completely freeze with RH2.1 update 3.
No logs, no dump, just hang. We have to reboot to be allowed to work again. This happens randomly even on the very last ML370 we just received weeks ago.
The problem doesn't occur with RH3.0 but we are stuck to the kernel 2.1-9 for an X25 board (eicon) certified for this kernel and software dev relying on it.
Do you know if there is paches to solve this problem.
Thanks for help

Hi all,
the freeze still exist but now i know how to replay it:
1) install a null modem cable between ttyS0 and ttyS1
2) cat /dev/ttyS1&
3) while :
do
cat /etc/inittab >/dev/ttyS0
sleep 10
done

The system freeze about 2 hours after the begining of the shell.
To get some dump :
modify sysctl.conf -> kernel.sysrq=1
Then sysctl -p
You need to disable X-Window (init 3,...)
That's it just wait for about 2 hours...
Is anyone having an idea to solve this.
Thanks
