I am running FC6 and keep at least one previous kernel around whenever I upgrade, but never had need of it until now. I want to revert from a 2.6.22 (IIRC -- not able to check right now) kernel to a 2.6.20 kernel to regain ACPI alarm wakeup functionality while the kernel devs are investigating how it got broken by their improvements.
<br><br>Now I find I need more knowledge to revert to the older one successfully.<br><br>I tried a manual override from the grub startup screen and it started to boot, but it froze when it got to starting the X font server (xfs), not to be confused with anything to do with the xfs file system.
<br><br>What do I do? How do I figure out what to do for the next complication (there's always room for one more ;-)<br><br>Craig.<br>
