SuSE Linux 10 choking on Adaptec RAID controller

In a flash of foresight, I decided to redo a SuSE 9.3 server that had not yet reached production to a SuSE 10.0 server. It’s a plain vanilla P4 3.0GHz server with 1GB of RAM, an Adaptec 2100S RAID controller and two Seagate Cheetah 10K disks. I’ve built and installed over 20 servers with this configuration without a problem, so I wasn’t quite expecting any problems with SuSE Linux 10.0. Yet the system came to a grinding halt upon the first reboot after installation.

I saw all kinds of error messages in the log, “iop0: device already claimed”, “iop0: DMA/IO allocation for I2O controller failed”, and so on..

I found this thread on the SuSE Linux Community Forum which helped immensly. Maybe it’ll help you too?

What can I say, I love Google 🙂
