Public bug reported: 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.
