Leonard,
This is a copy of a mail I sent a few days ago without having received any answer.
Can you pls have a look ? This problem is still pending and solved by the moment
with a system shutdown each 3 days. It feels that the more we keep the system without a shutdown the more we have this problem, but this remember me Window$ NT !!
Thanks is advance.

Hello Leonard,
The system with the eXtremeRaid 1100 adapter is working fine but from time to time it crash without reporting a trouble on /var/log/message
We have a "similar" system working in Geneva with different RAID controller: DPT SmartRAID
I suspect an I/O Interrupt problem. Do not ask me why. 25 years working with computers could be an answer.
We have already changed the mother board, as well as the two Pentiums. No difference. The system crash once each 8 or 12 days, then we need 4 hours to set it back. The Geneva system is working since weeks.
This is /proc/interrupts of the eXtremeRAID system:
0: 1485418 timer 1: 710 keyboard 2: 0 cascade 5: 1747992 + Mylex DAC1164P, + aic7xxx 7: 24 + BusLogic BT-930 8: 1 + rtc 10: 14 + BusLogic BT-930 11: 696449 eth0 13: 125959 + IPI 14: 1 + ide0
This is the /proc/interrupts of the DPT system:
0: 267415219 timer 1: 8730 keyboard 2: 0 cascade 5: 10862040 3c509 8: 1 + rtc 10: 316312 + BusLogic BT-948 11: 38399325 eth0 13: 1 math error 14: 13625063 + eata_dma 15: 6860687 + BusLogic BT-948
As you can see, on system eXtremeRAID interrupt 5 is shared between the 1100 board and the built in aic7xxx adaptec controller
What is your feeling about ? Is there something I can do to better analyze this problem ?
BTW, what is IPI ?
Regards
