SubjectDual Xeon Freezes with 2.4
Date
From
Hi folks,

I have a Dual Xeon box with Intel SE7500CW2 Server Board (eepro100 onboard) and a Promise SuperTrak 6000 RAID card,
and on running 2.4, the box freezes every now and then.

I am running thereby 2.4.18 (from Debian distribution) with I2O block driver to access the Raid-Card disks. It works fine, I can even boot from the Raid-disk, but as reported by others, the system freezes every now and then (only cold-reboot possible, resulting in a lot of disk errors)

[Q] Did somebody manage to run a stable 2.4 system on a similar Xeon Box, and if yes what compile or boot option did you use?

On running kernel 2.2.19 (from Debian distribution) , I have problems with the Raid-disks. Even though the I2O drivers recognize the Raid-Card it complains about not finding disks on block 50, and the boot stops by not finding the root.

VFS: Cannot open root device 50:01

Interestingly I2O under 2.4 maps the drives onto block 80 !!

[Q] Is there a difference in the I2O drivers between 2.2 and 2.4 ?
[Q] Are there option to map the I2O onto block 80 rather then block 50 ?

Promise has a source code for the SuperTrak 6000 card but I get a lot of compiling errors, that's why I use the I2O drivers.

On compiling 2.5.29 I get errors in several i2o*.c source-files. like

"#error Please convert me to Documentation/DMA_mappings.txt

and I am not Linux-experience enough to hack around in the source code. The documentation says something about DMA stuff (of course) but I am not sure what is required to enter in the sourec code.

[Q] Did anybody compile the 2.5 kernel with the I2O drivers, and if yes what should I change or enter in the corresponding I2O source files ?

[Q] Did somebody run the 2.5 kernel on a Xeon box and is it (more) stable ?

I appreciate any help and suggestion

!!!! As I am not subscribed to the list, so please CC any reply to my address as well, Thanks !!!!
Thanks & Cheers
Johannes
