Yes. I had applied the preempt patch to a pre-10 along with the xfs patch. I remember an additional patch was required to build but it was a simple include directive change, so I'm not sure if I used that minor patch or corrected it myself. Since then 2.4.10 came out and patches exist for it. Here's what to grab:
http://www.tech9.net/rml/linux/preempt-kernel-rml-2.4.10-6.patch (see also: http://www.tech9.net/rml/linux/) ftp://oss.sgi.com/projects/xfs/download/patches/linux-2.4.10-xfs-2001-10-03.patch.bz2 (see also: http://oss.sgi.com/projects/xfs/faq.html#xfspatches) and of course, http://www.kernel.org/pub/linux/kernel/v2.4/linux-2.4.10.tar.gz Unpack linux-2.4.10.tar.gz into some dir (not /usr/src unless you move the existing linux/ out of the way) then move the unpacked linux-2.4.10 dir across to /usr/src/linux-2.4.10 and symlink linux-2.4 (and maybe also linux) to linux-2.4.10. Then "cd /usr/src/linux" (you should be in /usr/src/linux-2.4.10 at this point). Well, you know what I mean... Then patch: bzcat /path/to/the/linux-2.4.10-xfs-2001-10-03.patch.bz2 |patch -p0 patch -p0 </path/to/the/preempt-kernel-rml-2.4.10-6.patch The patches should apply cleanly. Then "make mrproper", play with your default configs, then "make xconfig", "make clean", "make deps", "make bzImage" and then play with lilo.conf. I hope a preemptable kernel comes to a redhat distro soon. Matt On Fri, 2001-10-05 at 11:20, Michael Stack wrote: > Did you apply it to the 2.4.10 kernel?
