Interesting problem with 450NX based Compaq server
Hello, I've looked through the kernel list archives and haven't found anything that might help. I have a Compaq 5500r 4x500mhz Xeons and whenever a heavy load is placed on the box it reboots without any kernel panics or oops. It seems to be related primarily to multiple PCI card access, i.e. during heavy RAID card / NIC interaction. I've tried to isolate it by replacing NICs and RAID cards, but the only thing I can come up with is that it is related to the 450NX chipset. Since I am not sure anyone is still working on the 450NX chipset I've refrained from cluttering the list with a giant E-mail full of /proc data until someone answers back that they would be interested in any information that I can provide them.
Please CC me since I am not a list subscriber.
Thanks in advance.

I have an Intel ad450nx server, based on the 450NX PCISet chipset. 4x500MHz Xeons. It runs like a champ.
Maybe you have a buggy kernel. Try a vendor patch, or switch vendors, or try a kernel.org kernel or something like that?
I am running the latest 2.4.22 and still having the problem. Do you have any pointers for options that may need to be turned off in the kernel configuration?
I will try and get a new motherboard and see if that is the problem.

450NX does have bugs (browse the intel pdf). None of them I can see should bite people unless they are using mtrr ranges or have out of date bioses.
