irq 7: nobody cared

That is very good news.

I like to keep things as simple as possible, so removing all [i]unnecessary[/i] boot options is a sensible choice. Only by running the system for a while will you know the answer . . . :-)

Hello, now the sad news.

I had one machine crash yesterday,the kernel mesage wss "rejecting IO to offline device",
this has been the reason in the past where I added noapic to the kernel,
this nopaic causes the nobody cares message, adding irqpoll didnt make that message away,
Is there something else to prevent the kernel to disable the harddrives?

thx

That is unfortunate.

So the question is [i]What was the device that appeared to be offline to the kernel?[/i]

This may not be relevant but have you checked that you are using the latest available version of the BIOS for your system?

Anyone else care to comment or suggest ideas?

It is always the harddisk (a raid10 on a promise controller) that does offline.

well this weekend I tried to copy some file to that machine and it crashed 2 times during the transfer,
first time without "nopic irqpoll" and the second time with.

what can cause these crashes? It is about 200GB that need to be copied.

Could this issue ultimately be connected with that RAID controller? (I'm just throwing that question up into the air to see if one of my RAID knowledgeable colleagues will catch it.)
Other than that, I'm right out of ideas.

Hello Alan,

yesterday I did a BIOS update and also updated the BIOS and Firmware on the Promise Controller.
After 20 Minutes the machine did a crash, without any load.
I now removed the noapic and irqpoll, again.

Is there a way to see what driver version is running, i compiled a new one but maybe the latest version is already included with the centOS Kernel.

greetings

Heiko

To see what driver is currently built for the default kernel you could (as [i]root[/i]) [b]yum install kernel-devel[/b] (if not already installed), [b]cd /usr/src/kernels/2.6.18-92.1.6.el5-$(uname -m)/[/b] and [b]make menuconfig[/b].

My knowledge of things RAID is extremely limited. That is why I'm hoping others may be able to assist you.
