I understand now that instability concerns were responsible for the decision to remove the kernel low-latency patch beginning with the 2179 fedora core 1 release. And thank you for those explanations. However, I would like to suggest that for many of us this is an important patch, and there is actually no need to remove it altogether. This patch used to be equipped with a proc filesystem / sysctl control parameter, allowing the patch to be integrated into the kernel, and disabled by default. This would relieve the instability problems for the general populous, but allow users such as myself to easily enable the patch on systems where it is still needed. Yes, I know I could re-install the patch myself, but given the other changes that redhat routinely makes to the kernel, I have found it extremely difficult in the past to pick up the patch files and install them as is. We use the redhat distribution where I work, and it is very difficult at best to get "non-standard" patches installed by system administration personnel into their system installation procedures, especially patches that I have had to re-tailor by hand. Thank you, Matt Dunkle
