I've been using Andrea's 2.4.18rc4aa1 patches applied to a generic 2.4.18 kernel running on Intel 32-bit machines with 4GB of memory and usually some sort of Serversorks chipset with 1-2 CPUs of various speeds with great success for almost 6 months now. The primary base has been a SuSE 7.2 distro but others are now being tried, including Slackware 8.1 and RH 7.[23]. The principal reason for this was to use the 00_3.5G-address-space-4 feature. I apply all patches in the directory and have not seen a kernel failure yet with thousands of hours of "big process" CPU time logged across many machines. I consider this to be a pretty stable combination of kernel and patches for what I need.
RH's 2.96 gcc compiles fine but blows up or slows to a crawl (not unexpected) when big jobs are run and the machine starts paging. I've fixed this by putting a 2.95.3 gcc on the machine. I'll leave the editorial comments about 2.96-RH to others.
I'm trying to write some sanitized procedures which will allow me to pass this on to others. Non-2.96 distros (everyone except RH and Mandrake, AFAIK) have run fine without issues, mainly because they have a pretty stable 2.95 compiler included.
I will assume that a gcc 2.95 retrofit is required to make the -aa patches work on RH 7.[23].
What's the correct way to retrofit a 2.95.3 compiler onto an RH 7.[23] distro? Is it OK to just load it into /usr/local and build it? Does it require 'make bootstrap' to be entirely santized? Are there other GNU packages that I should be including with the gcc retrofit?
