Description Gilboa Davara 2006-06-20 08:54:11 EDT
Description of problem:
I'm trying to setup a xen setup on an HP xw9300 dual Opteron 275 (dual core)
workstation.
When the host tries to boot using the 2.6.16-1.2133_FC5xen0 kernel, the kernel
starts spewing huge amount of xen generated printks.

printk: 553 messages suppressed.

This report targets FC5, which is now end-of-life.

Please re-test against Fedora 7 or later, and if the issue persists, open a new bug.

Thanks
