Hi Folks, While performing "yum upgrade" the system had a Loop 1 kernel panic (interupt handler not syncing) whilst it was upgrading the kudzu package. When it rebooted it gave the same kernel error at the boot stage where it runs the kudzu script. I consequently used a rescue CD to disable the kadzu boot script; the system came back and "yum upgrade" went fine. However when I went back to reinstall the kadzu package (either from the 2.4.21-52.ELsmp or 2.4.21-53.ELsmp kernels) it fell over with the same kernel panic message, this also happens at boot time if I turn back on the kadzu init script. As the hardware on the system is unlikely to change I guess kadzu isn't really needed anyway, but I'm a bit worried this could be a symptom of a more serious issue. Anyone got any pointers or similar experiences? cheers, Ronnie -- ======================================================= Ronnie Wallace Department of Mathematics University of Strathclyde, Glasgow, Scotland =======================================================
