Xen kernel oops loading 3w-9xxx driver

[Mike Vincent]

I had been trying to bring up a new ubuntu server to use as a xen server using gutsy. Attempting to boot the xen kernel (after installing ubuntu-xen-server) I was unable to get past initramfs because the 3w-9xxx module would throw an error while loading.
Thinking that perhaps it was something that was fixed in the newer kernel I upgraded to hardy but received the same error...

The error is exactly the same as reported in this posting http://lists.xensource.com/archives/html/xen-devel/2007-09/msg00210.html
Follow through on the thread I patched drivers/scsi/3w-9xxx.c and recompiled and it seems to have fixed it for me.
The patch is very brief:

More info.

I ended up rebuilding the machine, this time using the amd64 netboot image (boot.img.gz) from http://archive.ubuntu.com/ubuntu/dists/gutsy/main/installer-amd64/current/images/netboot/

Unfortunately there's no ubuntu-xen-server meta package for 64, yet. :(

I installed linux-image-xen, xen-hypervisor, xen-utils-3.1 and all the things that get pulled in with, then rebooted and the xen kernel didn't have any issues with the 3w-9xxx driver.

So I presume the issues I had before were specific to using the xen kernel on a 32bit system.

i installed hardy too, and have the the same problem with the 3w_9xxx driver on 2.6.24-16-xen

Thank you for reporting this? Is this still an issue with an up to date Hardy installation?

Hello Caspar,

I can confirm that is is still an issue with an up to date Hardy installation. Just installed a fresh Hary and pulled "linux-image-2.6.24-19-xen" (well in fact took "linux-xen") from the repositories. When rebooting into xen now I run into the 3ware related error described here: http://lists.xensource.com/archives/html/xen-devel/2007-09/msg00210.html
