Description of problem: Dom0 cannot boot kernel-xen-2.6.18-92.1.17.el5.i686 (blinking cursor after GRUB) kernel-xen-2.6.18-92.1.13.el5.i686 boots correctly Version-Release number of selected component (if applicable): kernel-xen-2.6.18-92.1.17.el5.i686 How reproducible: Install kernel-xen-2.6.18-92.1.17.el5.i686.rpm and try to boot it on Dom0. Not all hardware is affected. Actual results: Dom0 does not boot at all, domU's boots this kernel ok. Expected results: Well it should boot...

Did anybody care to try the "original" RedHat build just to make 100% sure it's not a build issue of the CentOS build. We are using RHEL and CentOS on our servers but the affected one is CentOS for now and I simply can't risk to reboot it until I get close to the hardware (the box in question doesn't have any ILO whatever card). Would be nice someone could confirm that the RedHat build is also affected.
